# Finding electrical energy used by a light

**1. The problem statement, all variables and given/known data**

find electrical energy used by the light if the voltage on the battery is 110 V and the current in 2.0 minutes is 10 mA

V = 110

I = 10 mA

**2. Relevant equations**

R = V/I

**3. The attempt at a solution**

110 V /.010 A

= 11,000 ohms

= 11 k ohms

I’m new to this, did I do this problem right?
