Working Principle: When a current carrying conductor is places in magnetic fied, then the current carrying conductor experiences mechnical force. The direction of mechanical force in whcih the conductor move or rotate is given by Fleming’s Left Hand Rule Comparision between Motor and Generator: In both DC Generator and DC Motor emf is generated, hence […]

Voltage Source: Ideal Voltage Source: An ideal voltage source is one in which has zero internal resistance. Any volage source (battery) has certain internal resistance ‘r’ which cause the voltage drop. Current Source Ideal Current Source: An Ideal Current Source is one which delivers constant current irrespective of the load impendace. The connected load impedance […]
