A p-n diode has a reverse saturation current $1.44 \times 10^{-8} \mathrm{A} .$ It is forward biased so that it has a current of $6.78 \times 10^{-1}$ A moving through it. What bias voltage is being applied if the temperature is $300 \mathrm{K}$ ?

Welcome to the problem. Number thirty one point two zero. So this it's a pretty one ordinating current. We haven't allowed circuit the capacitance off the comm pasture and they never turned off uniter. And the assistance of very sister is given. So these are the they're loses. This is L. A and C and we have an issue source and this is his source has voltage elements. Is it cost you one twenty world and the frequency of this issue sources one point two five kilo heart. So between the couch. And so this is Serge. So we need to find out the power supplied by the tonality and power dissipation in their sister. And we have the formless here, so we will use these formulas here to find out the parameters. So let's find out the first we will find out the and the African searches on mebecause to pay f. So we have to buy times one point two five independence for our three because this is killer hurt. So this concert to be seven point it five for into dangerous to power three. But Etienne, farcical now finding out the exit then, doctor, A reoccurrence which is Omega and and putting the omega and l here. So this comes or Toby one five seven. Remember, this is twenty times than this. So minus three Hendry. And this is a cause to one forty time standards or minus nine. And this is because one I went to five unit and a score three heart now finding are the XY. So we have except cause to one of our own legacy. So we have a maid at this value and see where this wailing. So we put it back in this equation too. Once comes out of nine hundred nine. No. So we're done without coming parameters now that find out the average power. So we have then fight the face factor. Which is it cause to excel mine a sexy over our. So this gives us equals two one fifty seven minus nine zero nine. Or were three fifty and taking the Daniel's off this value. So fight comes out to be minus sixty five point zero for delivery. So this is over five now going tto find out the dead, which is the impudence of the circuit. So these are in Siri's, so we have so these. Aaron says we have Jerry question our square less excel minus x e hold square. So this comes out to be eight to be Joe. Now we need to find out the average power this epic it. So this is because to be Aramis, I reminisce, goes fi because to be anonymous, it's where we're jet course fight. So this comes out to be one twenty square for what, Jack, which is a thirty cause minus sixty five point zero four degree. So this comes out to be a selling point three two. What? So this is average? Participated. Now we need to find out the average poverty precipitation than a sister and a sister. So which is it cost to I r M s square? Oh, so this comes out to be one twenty square over eight, thirty square times three fifty. So we have vms. It goes to Isaac Otherness. So we have used this creation here to find out the Aramis. So we had our relative fifty own. So this comes out to be seven point three two. What? So this is the inside of this question. Thank you for watching the video

Have some givens. We have the induct insa 20 Miller Henry's or 20 times 10 to the negative. Third Henry's capacitance at 140. Nano Affair. It's a 140 times 10 to the negative ninth Ferrets. We have the resistance at 350 arms and the R. M s voltage at 120 volts and the frequency at 1.25 kilohertz I have converted to simply to hurt. So 1250 hertz We can find the implants in circuit. However, First we must find the reactive, the inductive reactant CE, which would be equal to Omega, multiplied by out. In this case, this would be to pi multiplied by the frequency multiplied by al where again omega. Here is the angular frequency of the circuit. This would be equaling to two pi multiplied by 1250 Hertz multiplied by the inductive of 20 times 10 to the negative Third Henry's and we find that the inductive react Ince's equaling 157 homes. The capacitive reactor Ince's equaling one over Omega Psi. This was equaling one over to pie times one my apologies. One over two pi times 1250 Hertz multiplied by 140 times 10 to the negative Ninth Farage's And we find that the capacitive reactor since is equally 909.45 homes. So we can say that the Impotence Z is gonna be equal to the square root of R squared Plus except l'm honest, except see quantity squared and plugging in. We have 350 homes, quantity squared plus 909 point knowing Two minus 157 Quantity squared. I'm squared. Extend the square root and we have our impotence is equaling. 830 comes now The R. M s current is equaling than the arms voltage divided by the impotence Izzy. This would be 120 volts, divided by 830 homes. And this is giving us 0.1445 amps. The power factor co sign co sign If I equaling the resistance in the resistor divided by Z the impotence this would be equaling 2 350 ums divided by 830 homes. And this is giving us 0.4217 So for part A, the powers supplied by the generator P would be equal in the arm s voltage multiplied by the arm s current multiplied by co sign of Fei or the power factor. And so this would be equaling two, 120 volts multiplied by 0.144 five amps multiplied by 0.4 217 And we have that The power supplied by the generator is 7.31 watts. Four part to be the voltage across the resistor. We can say that first, the voltage across the resistor would be the arm s voltages to be equal to the army's current multiplied by the resistance. This is equaling 2.1445 amps. This would be multiplied by 350 homes and this is giving us 50 0.6 votes. So the power dissipated in the resister. We can say piece of our This would be equaling to the R. M s voltage multiplied by the R. M s current multiplied by co sign of five power factor. And so the power dissipated in the resistor would be in 50 0.59 volts multiplied by 0.1445 amps multiplied by one. And this is giving us seven point 31 wants since the average power dissipated. And in the induct er's and the capacitors zero, uh, so whole power. So the entire power is dissipated, Uh, in the resistor. That is the end of the solution. Thank you for watching.

Similar to the problem. 61. The problem 62 states Dutch A germanium dired Ah, zero degree centric bridge. It's currently is 1.5 micro and PR on. Do we need to find out for the current at 104 C And ah, we know the information. Ah, given, as for every 13 degree centigrade increase, the current becomes double. So 1.5 macro NPR becomes three Michael impure on drugs and we can keep on going until 10 for because centigrade and we need to find out what is that current value at this? A temperature. Let us look at your what is a jump in the temperatures so we can see that so 104 by 13. So that begins eight times. So we have eight times jump Ah, in the current. So at every jump the current becomes double. That means the initial current value off 1.5 micro ampere has now increased due to the power eight times. So if we can calculate this 1.5 a micro NPR to dip our eighties to 56 that is equal to 384 micro and peer. So this is the current for germanium dialogue at once
