Answer to Question #103409 in Electricity and Magnetism for bjbnl

Question

How much work is done to transfer 2.6 C of charge through a potential difference of 120 V?

Answer 1

The potential of a field at a given point in space is equal to the work performed by electrical forces to transfer a single positive charge from this point to infinity.

$\phi = A/q$

$A=q*\phi$

$A = 2.6 * 120 = 312 J$

Answer: 312J
