    I would not recommend using "consume" as the word suggests current disappearing. The same way we consume food, the food is no longer there. But electrical appliances don't "consume" current by this same definition. The same amount of current goes in as comes out. The only change is the potential of the current (i.e. the current has less energy). Thus power is dissipated (heat is produced) within the appliance due to the current.
