Electrostatic Potential And Capacitance

Question

Name the physical quantity which has its unit joule coulomb^–1. Is it a scalar or a vector?

Solution

Poetential is defined as work done per unit charge.

∴ V = \frac{W}{q} = \frac{J}{C}

This implies, Joule per Coulomb is the SI unit of electric potential.
Electric potential is a scalar quantity.
