2. Electric Potential and Capacitance
medium

Distinguish difference between electric potential and electric potential energy

Option A
Option B
Option C
Option D

Solution

Electric Potential $(V)$ Electric Potential Energy $(U)$
$(1)$ Work done against electric field to bring unit positive charge is electric potential.  $(1)$ Work done against electric field to bring charge ' $q$ ' is electric potential energy
$(2)$ Unit : $JC$ $^{-1}$ or Volt. $(2)$ Unit : $J$ (Joule)
$(3)$ $\mathrm{V}=\frac{\mathrm{W}}{q}, q=$ unit positive charge. $(3)$ $\mathrm{U}=q \mathrm{~V}$
$(4)$ $[\mathrm{V}]=\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{-3} \mathrm{~A}^{-1}$ $(4)$ $[\mathrm{U}]=\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{-2}$
