Which quantity depends on the square of the current in Joule's Law?

Explanation:
Heat energy produced in a resistor grows with the square of the current because energy dissipated as heat is Q = I^2 R t. This means that, for a fixed resistance and a given time, doubling the current makes the heat quadruple. Emf and resistance aren’t described by a squared current in this law, and time scales energy linearly (through the t factor). So the quantity that depends on the square of the current is the heat energy.
