1.	Which of the follwing characteristies of electrons determines the current in a conductor?A. drift velocity aloneB. thermal velocity aloneC. both drift velocity and thermal velocityD. neither drift nor thermal velocity
Answer» The relationship between current and drift speed is given by `I=n eAv_(d)` Here `I` is the curret and `v_(d)` is the drift velocity. So, `IpropV_(d)` Thus, only drift velocity determines the current conductor.
