The energy transfer equation E = I x V x T uses which quantities?

The energy transfer equation E = I x V x T uses which quantities?

• A. Resistance and current
• B. Capacitance and voltage
• C. Current and voltage
• D. Inductance and current

Answer: (C)

Energy transfer in an electrical circuit is found by multiplying the power by the time the circuit runs. Power itself is the product of voltage and current, P = V × I. So the energy is E = P × T = V × I × T. This shows the quantities directly involved are current and voltage (with time as the duration). The other options—resistance, capacitance, inductance—don’t appear in this direct energy expression; they affect how current and voltage behave but aren’t the factors being multiplied to yield energy in this formula.
