Question
Consider the three circuits shown above. All the resistors and all the batteries are identical and ideal. (For each statement select T True, F False). A) The current through a resistor is the same in circuits A and C. B) The voltage across a single resistor in circuit C is equal to the voltage across a single resistor in circuit B. C) The power dissipated in circuit A is twice the total power dissipated in circuit B. D) The current through the upper resistor in circuit B is half the current through the resistor in circuit A. E) The total power dissipated in circuit C is twice the total power dissipated in circuit 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)
