A ring of radius r is rotating about its diameter with angular velocity `omega` in a perpendicular magnetic field `vecB` It has 20turns.The emf induced
A magnetic field `2xx 10^(-2) T` acts at right angles to a coil of area `200 cm^2` with 25 turns. The average emf induced in the coil is 0.1 v when it removes from the field in time t. The value of t
A coil has an area of 0.05 m2 & it has 800 turns. It is placed perpendicularly in a magnetic field of strength , `4xx10^(–5) Wb/m^(-2)`. It is rotated through `90^o` in 0.1 sec. The average emf induced in the coil
When 100 volt dc is applied across a coil, a current of 1A flows through it. When 100 volt ac at 50 cyle `s^(-1)` is applied to the same coil, only 0.5 A current flows. The impedance of the coil
A coil of inductive reactance `31Omega` has a resistance of `8Omega` . It is placed in series with a condenser of copacitive reactance `25Omega` . The combination is connected to an a.c. source of 110 volt. The power factor of the circuit
