## Homework Statement

A typical electric blanket consumes 50 W of power when operating. What is the overall resistance of the blanket if it is designed to be plugged into a standard powerpoint?

Power = 50 watts

Voltage = 240 v (standard powerpoint)

## Homework Equations

I (current) = Voltage/ Resistance

Power = V x I

## The Attempt at a Solution

So we are trying to find the overall resistance:

R = V/I

R = 240/I

P/V = I ?

50/240 = I ?

I = 0.2083333 (I don't think that looks right)

So then, R= 240/0.2083333

R= 1152??

Resistance is 1152 ohms?

These answers seem very strange to me and I am uncertain as to whether my logic is sound or not.

If my logic is incorrect, could someone inform me of the logic of the correct way? Thanks!
