Question

For a constant voltage, the electrical power is directly proportional to.

• A. electric resistance
• B. temperature
• C. electric current

Answer 1

The correct option is C electric current

According to relation: Electric power $\text{P}=\text{V}\times \text{I}$, where, $\text{V}$ is the voltage and $\text{I}$ is the electric current, for a constant voltage, the power is directly proportional to the current.
