Question

if C is capacitance and R is resistance, then calculate the possible units of CR^2

Answer 1

it is known that constant of RC circuit is t = RC and time constant of LR circuit is t = L/R.

therefore RC = L/R or CR^2 = L

HENCE THE UNITS OF CR^2 ARE THOSE OF INDUCTNCE(L) VIZ. HENRY

from e = L dI/dt
L = e dt/dI

units of L = ohm - sec

again E = 1/2 LI^2 , L = 2E/I^2
therefore units of L are also joule/ampere^2
