What are watts according to the material?

• A. A unit of resistance
• B. The rate of charge storage
• C. Watts = Volts × Amps
• D. A measure of force in a circuit

Answer: (C)

Watts measure electrical power—the rate at which energy is transferred or used in a circuit. This power comes from multiplying the voltage by the current, so P = V × I. That means watts tell you how quickly energy is being delivered, not how much energy is stored. The other options mix up different electrical ideas: resistance is measured in ohms, not watts; charging rate isn’t described by watts alone; and force isn’t a standard measure used for circuits. So the statement that watts equal volts times amps correctly defines watts.
