Homework Statement

How much energy is dissipated as heat over 2 minute time interval by a 1.5 k(ohm) resistor which has a constant 20 V potential difference across its leads?

Homework Equations

deltaV=-Ed

The Attempt at a Solution

In my notes this is the only equation that seems like it might work here. I assume I probably have to use some other equations to figure out the d

deltaV=-Ed

The E in this formula is electric field, which you don't have in this problem.
You need a formula for electric energy or a more general one relating power with energy along with a formula relating power with voltage and resistance.
