A resistor is wired to a battery in a circuit and dissipates a power P₁ as heat. A second battery, with the same voltage, is added in series with the first battery, leading the resistor to dissipate a power P2 as heat. How much does the resistor dissipate with two batteries, relative to with one battery, or in other words, what is the ratio P₂/P₁?
