- Homework Statement
- A light dependent resistor is connected across an ideal 12 V source

and placed in the open in the middle of a desert. When is the power

dissipated in the resistor highest?

A )dawn B) mid morning

C) noon D) midnight

- Relevant Equations
- P= IV --> P= I^2 R ---> P = V^2/R

Which equation do I use and why do I use it? I think it would be P = V^2/R, but why do we exclude current the from the equation?
