Question
1. For the circuit in Figure on the right, find (a) the equivalent resistance of the network, (b) the current through each resistor, and (c) the power supplied by the battery R. = 10 R3-30 K, 5011 2. Find the equivalent capacitance between points a andb for the group of capacitors connected as shown in Figure below if CI = 5.00 F, C2 1 0.0pF, and C3-2.00 F. Cs Cz Consider the combination of capacitors in Figure on the right. 3. 24.0 1 (a) What is the equivalent capacitance of the group? (b) Determine the charge on each capacitor 8.00 !Explanation / Answer
1 a] equivalent resistance = R1 + 1 / [1/R2+1/R3+1/R4]
= 12 + 1/[1/10+1/30+1/50]
= 18.52 ohm
b] i = V/Req = 48/18.52 = 2.59 A
CURRENT i1 = 2.59 A,
i2 = V2/R2 = [48 - 12*2.59]/10 = 1.692 A
i3 = V2/R3 = [48 - 12*2.59]/30 = 0.564 A
i4 = V2/R4 = [48 - 12*2.59]/50 = 0.338 A
c] power supplied by battery= iV = 2.59*48 = 124.3 W answer
