What work is done when 5.0 C is moved through an electric potential difference of 1.5 V?

Work done= VIt
= V* amount of charges
= 1.5V * 5.0 C
= 7.5 J of work done

V=voltage
I= current
t= time
It= amount of charges (coulombs(C)

By definition on electric potential the work done is W = qV Thus W = 5.0C x 1.5 V = 7.5 Joule

ÎV = -W/q

W = -qÎV

W = -(5.0 C)(1.5 V)

W = -7.5 J
