What is voltage in simple terums

VOLTAGE

The electromotive force (emf) is a measure of the strength of a source of electrical energy. Emf is not a force in the usual mechanical sense, but it is a convenient term used for the energy which drives current through an electrical circuit.

When two charges have a difference in potential,the electric force that exists between them can be called the electromotive force (emf) .

## The force which sets up a flow of current in a circuit or a conductor is called emf.

Its symbol is E and its unit is Volt.

1 volt = 1000 milli volts.

V = voltage (volt) V = I*R

I = current (ampere) R = V/I

R = resistance (ohm) I = V/R

## The terms potential, electromotive force (emf) , and voltage are often interchangeably used.

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 are the types of filter circuits

FILTER CIRCUIT FILTER Filter is an electronic circuit. Filter circuit is very useful electronic device which can filter pulse of frequency. Filter circuit can stop or pass particular band of frequency. TYPES OF FILTER CIRCUIT 1)Low pass filter circuit. 2)High pass filter circuit. 3)Band pass filter circuit. 4)Band stop filter circuit. 1)LOW PASS FILTER CIRCUIT Low pass filter circuit This filter circuit allow only low frequency and which reject above the all cut-off frequencies its called low pass filter. NAME OF THE COMPONENTS WHI...

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...
