A coil of inductance 318.3mH and negligible resistance is linked in series with a 200 resistor to a 240V, 50Hz supply.
Calculate
(a) The inductive reactance of the coil,
(b) The impedance of the circuit,
(c) The current in the circuit,
(d) The p.d. across each component, and
(e) The circuit phase angle.

SKIPPING IS A WHAT TYPE OF MOTION
the magnetic field at a dictance of 2cm from the axis of a straight conductor carrying current is 12mT.Find the currentin the conductor?
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of
Q. Give any three properties of electric lines of force. Properties of lines of forces: (i) Lines of force begin from positive charge and terminate at negative charge. (ii
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.
Q What is electromagnetic induction? The phenomenon of producing an induced emf because of the changes in the magnetic flux associated with a closed circuit is known as electr
What is Heat? We now have several scales for measuring temperature, but first let's ask, “Is temperature the same as heat?” If I add heat to a pot of water, the water's temperatu
