Question
Circuit A has one resistor and one battery. Circuit B has two resistors in series and one battery. Circuit C has two resistors that are parallel with one battery. All resistors and all batteries are identical.1. The power dissipated in circuit A is twice the power dissipated in circuit B.
2. The current through a resistor is the same in circuits A and C.
3. The current through a resistor is the same in circuits A and B.
4. The voltage across a single resistor in circuit C is twice the voltage across a single resistor in circuit B.
5. The total power dissipated in circuit C is twice the total power dissipated in circuit B.
