The potential is the highest near the positive plate the potential is the highes

Question

The potential is the highest near the positive plate the potential is the highest near the negative plate the position between the plates does't affect the potential For problems 6-15, you need to SHOW YOUR WORK, and may get partial credit if your work demonstrates your understanding of the concepts. A 8.00 mu F capacitor and a 10.0 mu F capacitor are connected in series, What is the equivalent capacitors of the combination? Charge flows through a wire according to the formula q(t) = 5 + 4.3 t + 2t^2 Determine the equation for the current as a function of the (units can be left off here) For the circuit shown to the right, indicate the potential value at each corner of the circuit assuming that the negative terminal of the battery is at 0 V.

Explanation / Answer

Ans :-

6] C1 = 8 µF C2 = 10 µF series in combination

1/ Ceq = 1/C1 + 1/C2

            = C2 +C1 / C1*C2

Ceq = C1*C2 / C2+C1 = 8*10^-6 * 10*10^-6 / 10*10^-6 + 8*10^-6

Ceq =4.44*10^-6 = 4.44µF

7] q(t) = 5+ 4.3t + 2t^2

I(t) = dq /dt = 0 + 4.3 + 4t

I(t) = 4t + 4.3

8] i = v/ R1 + R2 + R 3 = 12 / 1+ 1+1 = 4A

V = i *R = 4*1 =4v

Potential value at each corner is 4v
