Q.1.STATE THE ACTIVITY THAT RELATES TO OHM S LAW

Open in App

Solution

If I current flowing through a conductor is directly proportional to potential difference across the ends of the conductor
V is PROPORTIONAL to I

$v_{d} = u + a t 0 + \frac{F}{m} t = \frac{e E}{m} τ b u t E = \frac{V}{L} S O v_{d} = \frac{e V}{m L} τ A L S O I = n e A v_{d} = n e A (\frac{e V}{m L} τ) = \frac{(A n e^{2} τ)}{m L} V \frac{V}{I} = \frac{m L}{A n e^{2} τ} = R (C O N S T A N T) H E R E A B O V E V = P O T E N T I A L D I F F E R E N C E, I = C U R R E N T A = C R O S S S E C T I O N A L A R E A, τ = R E L A X A T A T I O N T I M E n = n o o f e l e c t r o n p e r u n i t v o l u m e, m = m a s s o f e l e c t r o n e = c h a r g e o f e a c h e l e c t r o n$
