What is meant by DC current

The term direct current (DC) supply is given to a supply source that makes current to flow 
through a circuit in one direction only.

       Batteries and some types of generators give DC supply of constant voltage.

   ## DC supply is not distributed by electric supply agencies in India.















     Advantage of DC supply
  
     1) D.C is better for electric arc-welding.
     2) D.C is essential for electroplating.
     3) D.C is essential for the operation of various electronic equipment .

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 ยต 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...
