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. [Figure 33.1] Which word equation must be correct?
Apower dissipated in R₁ = power dissipated in R₂ + power dissipated in R₃
Bpower dissipated in R₂ = power dissipated in R₃
Cpower output of cell = power dissipated in R₁ + power dissipated in R₂ + power dissipated in R₃
Dpower output of cell = power dissipated in R₁
