A potential difference ' $\displaystyle V$ ' is applied across a load resistor of resistance $\displaystyle R$. V and R can be varied. If the current that flows in the circuit is I , draw a plot showing the variation of power consumed by the resistor as a function of:
(a)
R, keeping V constant
(b)
I, keeping R constant
(c)
V, keeping R constant
