The power factor of an a.c. circuit having resistance R and indctace L (connected in series) and an angular velocity omega
State Ohm’s law. Derive the laws of resistance, when they are connected in series
The resistance of each arm of the wheat stone bridge is 10Omega . A resistance of 10Omega is connected in series with galvanometer then the equivalent resistance across the battery will be
n conductors, each of resistance r, when connected in parallel, give an effetive resistance R. What will be resistance, if they are connected in series?
What is the need of combining different resistors? What is the resultant resistance when number of resistances are connected in series?
