A non-conducting ring of radius $r$ has charge $q$ distributed uniformly over it. If it rotates with an angular velocity $ω,$ then the equivalent current is

Options:

Answer:

Solution:

Non conducting charge ring rotates with an angular velocity ω is equivalent to electric current

$I = \frac{q}{T}$ = $\frac{q v}{2 π r}$ = $\frac{q r ω}{2 π r} = \frac{q ω}{2 π}$
