An appliance rated $440 {\W}, 220 {\V}$ is connected across $220 {\V}$ supply.

Question : 32 of 45

Marks: +1, -0

Calculate the maximum current that the appliance can draw.

Solution:

\;\;\text " Given : "\; \;\; P=440 {\W} ; V=220 \;\text " Volt "\;

\; ∵ \;\; {\P}= {\VI}

\; ∴ \;\; {\I}=\;{ {\P}}/{ {\V}}=\;{440}/{220}

\;=2 {\A}
