What is the current in milliamperes produced by the solar cells of a pocket calculator through which 4.00 C of charge passes in 4.00 h?

So in this problem, we know that in four hours. So there is a totally folk forms of charge of passing through, so we can see the current equal four columns. Bye bye for our worst times the 30 600 seconds per hour. Okay, so this gives you the current and we want to figure out to the power. So power equal to V times I write. And we already know that I'll put a output of the body tickle to three votes. So is simply plugging the two values. And we can see that the power equal 8.3 times turned to the navy. Fourth warts.

So in this problem, we have a solar cell Which provides an M4, 0.45 holds. So this solar cell is providing constant current of A 10 million people for nine odds. So converting these two units in standard unit would give us 18-24 -3 and fear and miners would be 3-400 seconds. So first in part we would we would be calculating the electrical energy. Electrical energy is mm. Thanks current. Thank don't. So mm 0.45. Yeah, Current is 18 intravenous for -3 Time is 3- 400. So electrical energy is 2 6, 2.44 jewels in part B. Well, to find the power, the rate at which electrical and as he is provided. So P is equal to he into I Is 0.45. current is 18 to 24 see. So this would give us 8.1 merely what

In this problem. We have a solar cell with an electro motive force of 0.45 volts. If you've sell supplies a current, uh, 18 Milly amps, which is the same as 18 times 10 to the negative third amps for a time of nine hours. How much energy does it supply? So we're going to be using the equation. Energy is electric force times a charge. We don't know the charge, but we do know that the current ego, the charge over the time we have the time and we have the current. So we just rearrange it to find the charge. Current is 18 times 10 to the third times. Nine hours. We convert that seconds 60 time 60 and we get 5 80 three cool arms. We go back to our equation. 0.45 bolds times 5 83 Cool ums, and we get 262 0.4. Jules, pray next we have to find the power. Power is w over t work over time, work or energy. The same electrical force times at the time. Times a charge. Excuse me, and we know that que or charge equals current times time. So we put that into the equation. We get electro motive force times, current times time divided by time These cancel out and we saw 0.45 times the current, which is 0.18 and we get 8.1 times 10 to the negative three watts.

In this problem battery word age, that is B is given as 1.35 holes and current, which flows he's off, See you 0.2 million peers and we need to calculate the effective distance of a pocket calculator. Now, in order for us all this we can use simply over So which is really easy Quote, too. I'm working, played by our. So therefore, if you want to calculate the value of resistance, which is that a Shall we try? We is given as 1.35 wars and guarantees of zero point to media that is tinnitus to minus three young beers so on so that we get as 67 Fi CEO that has excelled in 750. So therefore, effective resistance could build it in a 6.75 plumes so they figure a distance off a pocket calculator is off. 6.75 killed
