A calculator is rated at 017 Wwhen con nected to 440 Vbatter

A calculator is rated at 0.17 Wwhen con-

nected to 4.40 Vbattery.

What is the resistance of thisdevice?

Answer in units of .

Given :

Power P = 0.17 W

Voltage (V) = 4.40 V

We know that :

P = V² / R

or R = V² / P = (4.40)² / 0.17 = 113.88

Hope this helps u!
