A resistor with resistance $R$ carries current $I$ when the potential difference (p.d.) across it is $V$. The resistor dissipates power $P$. If charge $Q$ passes through the resistor, work $W$ is done. Which of these relationships among the variables is not correct?
- A$I = \frac{P}{V}$
- B$Q = \frac{W}{V}$
- C$R = \frac{P}{I^2}$
- D$R = \frac{V}{P}$
