Physics energy (I'm confused help)

What is the formula for work done when a current flows?
I have it written somewhere that it is pd x current x time but I can not find anything on the internet. Is there even a formula????
Thanks

Work done = Energy Transferred.
E = Charge * Voltage
Or Power = Voltage * Current so
Power = Enrgy/ Time
Energy = Voltage * Current * Time

Work Done is the electric potential (v) which is W/Q ( work done on that charge to bring it there from infinity)

Therefore W = V x Q

Substitue Q = I x T

Therefore W = V x I x T
