Effect of Internal Resistance on Power
A battery with an emf of 24.0 V and an internal resistance of 2.0 Ω is connected to a resistor network with an equivalent resistance of 6.0 Ω. If the battery is replaced by an ideal voltage source of 24.0 V, by what factor does the power dissipated by the resistor network change?
