How do you find the p.d across a resistor?

Asked by Timebomb (240points) December 21st, 2009

Lets say I have a series circuit, 10v flowing through, two resistors one being a 2 ohm another a 3ohms.

What’s the p.d. across the 2ohm resistor?

I’m more interested in knowing how I work this out than the answers but what ever way helps in explaining it to me would help.
