The current through a certain heater wire is found to be fairly iA 3.0-A current is maintained in a simple circuit that consists of a resistor between the terminals of an ideal battery. If the battery supplies energy at a rate of 25 W, how large is the resistance?ndependent of its temperature. If the current through the heater wire is doubled, the amount of energy delivered by the heater in a given time interval will
