Resistance = (voltage) / (current)

                     = (220 V) / (4 A)  =  55 ohms .

(Where exactly do you use 220 V in your car ? ! ?)

Explanation:

Given that,

Voltage, V = 220 V

Current, I = 4 A

We have to find the resistance of the appliance.

Ohm's law gives the relation between the current, resistance and the voltage.

V = I R, R = resistance

So, \(R=\dfrac{V}{I}\)

\(R=\dfrac{220\ V}{4\ A}\)

\(R=55\ \Omega\)

Resistance of the appliance is  \(55\ \Omega\).

Hence, this is the required solution.
