(A) The relationship between power $(P)$,voltage $(V)$,and current $(I)$ is given by the formula $P = V \times I$.Assuming the voltage $(V)$ remains constant (as in a household supply),the power $(P)$ is directly proportional to the current $(I)$: $P \propto I$.Therefore,an electrical appliance with higher power will draw a larger current from the source.
