Current flowing through a conductor produces heat. This heat depends on quantity of current flowing through the conductor, time and […]

Three sums of electrical power have been discussed in this video. This is the second part of sum discussion .

    Three sums of electrical power have been discussed. Here. This sum will give a basic idea of finding

Rating of Electrical Appliance:These are normal rating of electrical appliances available in the market. Electric bulb-100W, 60W, 15W Fluorescent tube-

Th S.I. unit of energy is joul(J). Let the power (p) of an electrical appliance = P wattLet it is

Electrical Power: Rate of electrical energy supplied by a source e.g. a power station or an alternator or a dc

Ohm’s Law: It can be defined as “The potential difference (P.D.) across a conductor is proportional to the current flowing

Suppose a Current I flows through a circuit as shown in the figure. The voltage across the resistance is V

Emf: Emf is defined as work done per unit charge in taking a positive charge through the complete circuit (

Resistance: Resistance of a conductor is the opposition offered by the conductor to the flow of current through it. Resistances
