Electrical current and Resistance and Energy
1. The problem statement, all variables and given/known data
A 12v battery causes a current of .60A through a resistor. a) what is the resistance? and b) how many joules of energy does the battery lose in 1 minute?
2. Relevant equations
R= V/I; I= Q/T
3. The attempt at a solution
I understand part A that is just algebra and I got 20 ohms,
but I dont know how to translate this into energy lost. Can I use that second equation somehow with 60 seconds?

never mind i figured it out i was dividing instead of multiplying!
