Question

Valerie's 170 W electric rollers are plugged into a 200 V line in her bedroom. What current do the electric rollers draw?

Answer 1

Given data

*The given power of the electric rollers is P = 170 W

*The given voltage is V = 200 V

The formula for the electric current of the electric rollers draw is given as

`I=(P)/(V)`

Substitute the known values in the above expression as

`\begin{gathered} I=(170)/(200) \\ =\text{0}.85\text{ A} \end{gathered}`

Hence, the electric rollers draw the electric current is I = 0.85 A
