- Homework Statement
- (a) Derive an expression for power in terms of potential difference and current.

(b) Use the result from part (a) and Ohm’s law to derive an expression for power in terms of current and resistance.

- Relevant Equations
- p= E/T

V=E/Q

I=Q/T

e=QxV

t=Q/I

p=(QxV)/(Q/I)

=V/I

The expression I came up with for a) is the potential difference divided by current to get power but I have no idea if that is even right if someone could just prompt me in the right direction that would be greatly appreciated
