Question

What is the current when a 200Ω appliance is plugged in to the wall?

Answer 1

Answer:1.1 A

Explanation:

Given

Resistance of appliance $R=200\ \Omega$

We know common house hold voltage in India is $220\ V$

and according to ohm's law

$V=IR$

So, current

$I=\frac{220}{200}$

$I=1.1\ A$
