Electrical Circuits Homework Help?

Vince Delarge: @Eng. Magnolia, thanks for your help i still don't get #1 though.

Clinton Quant: I think you have something wrong with the first question, since P=IVand P=dw/dt, W is given by 500MJ, and the time is 1 week so you should calculate the number of seconds in one week then differentiate the energy in order to find the power and then find the current using the formula: I=P/V.2. Seems right.3. Just differentiate the charge (Q) with respect to time, since I= dQ/dt.4. I= q/t. V= W/q.P=w/t=V.I.a) Q= I*t= 1500 mAH.b) W= V*Q= 1.5*1.5= 2.25 Jouls.5. Correct answer.Hope I helped.Good luck..,...Show more
