Question
Consider the three Where A has a single resistor B has two resistors in Series and C has to resistors in parallel All the resistors and all the batteries are identical and ideal. (For each statement select T True, F False). A) The current through the left-hand resistor in circuit C is half the current through the resistor in circuit A. B) The current through a resistor is the same in circuits A and B. C) The power dissipated in circuit A is twice the total power dissipated in circuit B. D) The voltage across a single resistor in circuit C is twice the voltage across a single resistor in circuit B. E) The total power dissipated in circuit C is four times the total power dissipated in circuit B. (Explain why)
Explanation / Answer
A) The current is same in all the resistors however, in parallel circuit, the currents is to be supplied to two resistors so it should be half in each of the resistors.
B) False - current in A is twice the current in B
c) True - as Power is equal to I2R, it is true.
D) True - In series circuit, current is same but voltage gets divided but in parallel, voltage is same but current gets divided.
E) True - See the power dissipated formula. The current in circuit B is half that of that in one resistor in circuit C. The total current in circuit C is twice that of the current in one resistor.
