Which of the following statements are true about electric power and electric potential energy? List all that apply. Power is the amount of energy used by an electrical appliance. Power is the rate at which energy is used by an electric circuit. A kiloWatt•hour is a unit of electric power. A Joule/second is a unit of power. A 60-Watt light bulb would consume 30 Joules of electrical energy in 2 seconds. A 120-Watt light bulb would consume 1200 Joules of electrical energy in 6 seconds. A charge moving through an electric circuit would gain electric potential energy in the internal circuit and lose electric potential energy in the external circuit. Charge has the greatest amount of electric potential energy at the - terminal of the battery. If a 60-Watt light bulb is placed in a 120-Volt circuit, then the current in the light bulb is 2 Amps. Consider two light bulbs with different power ratings. A 60-Watt light bulb has a greater resistance than a 100-Watt light bulb.
