A cell of negligible internal resistance is connected to resistors R1, R2 and R3, as shown. The cell provides power to the circuit and power is dissipated in the resistors. Which word equation must be correct?

1. Apower dissipated in R1 = power dissipated in R2 + power dissipated in R3
2. Bpower dissipated in R2 = power dissipated in R3
3. Cpower output of cell = power dissipated in R1 + power dissipated in R2 + power dissipated in R3
4. Dpower output of cell = power dissipated in R1
