a resistor connected to a 1.5 v battery dissipates 1.0 w. if the battery is replaced by a 3.0 v battery, the power will be

The power dissipated in the second case is 4W.A resistor in a circuit with a voltage drop consumes electrical energy. All resistors have a power rating because this electrical energy is converted to heat energy. This is the maximum power that can be drawn from the resistor without burning out. Resistor energy dissipation. A charge q moves through a resistor, it loses potential energy Vq. where V is the potential drop across the resistor.This energy is dissipated as heat similar to how a ball of putty falling off a cliff converts potential energy into heat when it hits the ground. When current flows through a resistor, electrical energy is converted into heat energy. All heat generated by the components of a circuit has at least some resistance and is dissipated into the air surrounding the component.Learn more about A resistor here:-https://brainly.com/question/24858512#SPJ4
