Question

Consider the three circuits shown above. All the resistors and all the batteries are Identical. The total power dissipated in circuit C is twice the total power dissipated In circuit B. The power dissipated in circuit A is twice the power dissipated In circuit B. The voltage across a single resistor in circuit C is twice the voltage across a single resistor In circuit B. The current through a resistor is the same In circuits A and C. The current through a resistor is the same In circuits A and B. Submit Answer Tries 0/7

Explanation / Answer

a. power dissipated in C = V^2/Req = 2V^2/R [ Req = R/2, parallel connection]
power dissipated in B = V^2/Req = V^2/2R [ Req = 2R, series connection]
Hence False statement
b. Power dissipated in A = V^2/R
Power Dissipated in B = V^2/2R
Hence True
c. V across R in B = V/2
V across R in C = V
Hence True
d. Current through ckt in A = V/R
Current through R in C = V/R
Hence True
5. I through A = V/R
I through R in B = V/2R
Hence False
