Question
Consider the three circuits shown above. All the resistors and all the batteries are identical. The current through a resistor is the same in circuits A and C. 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 total power dissipated in circuit C is twice the total power dissipated in circuit B. B The current through a resistor is the same in circuits A and B.Explanation / Answer
1. False because R in circuit C is 1/4 of that of R in circuit B 2. True . Vc = V and Vb= V/2 3. Yes . I =V/R 4. NO. I = V/2R in B 5. YES. Pa = V^2/R , Pb= V^2/(2R)
