On connecting a resistor to an alternating EMF the oscillations of V and I are said to be driven or forced. Why??
Asked by ARATHI M | 25 Nov, 2013, 04:22: PM
answered-by-expert Expert Answer
I AC circuits,oscillations of charge, current and potential difference is called driven or forced oscillations.
 
When alternating emf is applied to a resistor, voltage and current are in phase with each other.
The minima, zero and maxima occur at same respective times. There is no damping in the amplitude of voltage and current.
