Relation between work and voltage

The Work from Voltage and Charge calculator computes the work associated with an electric potential (E) and a charge (q).

INSTRUCTIONS: Choose units and enter the following:

• (E)  This is the voltage.
• (q)  This is the charge.

Work (W): The calculator returns the work (W) in Joules.  However this can be automatically converted to other work units via the pull-down menu.

The Math / Science

The relation between work and voltage^[1] equation calculates the work done or required when a charged particle passes through a charged area. An area full of electric charge is called electric potential, where the charged particles that pass through the area are either repelled or attracted. When a particle moves from point a to point b, the energy (specifically work) needed move that particle through the charged area is called electric potential difference. The greater the distance between point A and point B, the more work is needed to be done. 

The equation for work from volts and charge is:

                             Work = E * q 

where: 

• Work is in units of (Joules)
• E is the potential difference in units of (volts)
• q is the charge in units of (Coulombs)
