☆Hey friend!!!! ☆

==================
Here is your answer ☞
==================

$given \\ \\ voltage = v = 220 \: v \\ power = p \: = 22 \: kw \: = 2.2 \times {10}^{3} \: w \\ time = t = 3 \: h \\ \\ now \\ \\ electrical \: energy \: = e = p \times t \\ \\ = > e = 2.2 \: kw \times 3 \: hr \\ \\ = > e = 6.6 \: kwhr \: .......answer \\ \\ now \\ \\ current \: drawn \: = l = \frac{p}{v} \\ \\ = > l = \frac{2.2 \times {10}^{3} }{220} \: a \\ \\ = > l = 10 \: a \: \: \: \: .......answer$
