Solar Battery Charger Circuit

Michelle Said:

What do I, C, and T stand for in science? ?

We Answered:

Yes, the choice of letters is a bit odd.

Anyway, the way you have it written, I represents the energy storage capacity of a battery, C represents the amount of current that you are taking out of the battery and T represents the time.

Your equation is just saying:

"If the battery holds 2100 mA-hours of electricity and you are drawing 10 mA, then it is going to last 210 hours"
