Emf is synonymous with wattage according to the material.

Explanation:
Emf represents electromotive force, a potential energy per unit charge that a source can provide, measured in volts. Wattage, or power, is the rate at which energy is transferred and is calculated as voltage times current (P = V × I), measured in watts. These are different ideas: emf is about the energy available to push charges, while wattage is about how much energy is actually being used or delivered per unit time given a current. Because current and any internal resistance of the source affect the actual energy flow, emf does not equal wattage. So the statement is false.
