What is flow of electric current

The motion of electrons is called electric conduction electric current. When No external energy is supplied the free electrons in a conductor move from atom to atom within conductor.

When the conductor is considered as a whole, from one end to other end the current is zero.

The external force is given to these random moving free electrons , the motion of electrons will be organised of the movement of electrons in a particular direction through the wire.

This is called flow of electric current.

What is Resistor and its used

RESISTOR Resistor Resistors are electronic components, used to reduce, of limit, or resist the flow of current in any electrical or electronic circuit. RESISTANCE The property of the resistor to limit the flow of current is known as resistance. UNIT OF RESISTANCE The value, or quantity of resistance is measured in units called ohms. Resistors are called passive devices because their resistance value does not change even when the level of applied voltage or current to it is changed. The resistance value remains same when the applied voltage is AC or DC. SOME RESISTANCE VALUE 1000 ohms = 1 kilo ohms 10000 ohms = 10 kilo ohms 100000 ohms = 100 kilo ohms 1000000 ohms = 1 mega ohms TYPE OF RESISTORS 1) Carbon Resistor 2) Wire Wou...

What is inductance and its formula

INDUCTOR Inductor are passive components consisting of coil of wire. The basic function of inductor is to store electrical energy in the form of magnetic field, when current flows through the inductor. INDUCTANCE Inductance is the electrical property of Inductors. The property of A.C circuits which opposes any change in the amount of current is called inductance. UNIT IF INDUCTANCE Its symbol 'L' and unit is 'henry' (H). HENRY If a current changing at the rate of one ampere second , induces and average e/m/f of one volt in a conductor, the amount of inductance in the conductor will be one henry. 1x10 -3 Henries = 1 Milli Henry =1mH 1x10 -6 Henries = 1 Micro Henry = 1 µ H 1x10 -9 Henries = 1 Nano Henry = 1nH Applications of Inductors Tuning cir...

What is a battery

CELL AND BATTERY BATTERY Battery Battery is chemical energy convert to electrical energy. TYPES OF CELL Cell is two types------- 1)Primary cell 2)Secondary cell 1)PRIMARY CELL A cell which convert chemical energy to electrical energy.It is active few hours and then stop working. Primary cell is not rechargeable. TYPES OF PRIMARY CELL 1)Voltaic cell 2)Daniel cell 3)Leclan...
