Alternating Current and Direct Current

Full form of AC & DC

100

end to end connection forms series connection.

what is series circuit?

100

Transformer is a static electrical device which transfer the electrical power from one circuit to another circuit with desired change in voltage and current but not in frequency.

what is transformer?

100

Converts Mechanical energy into Electrical energy.

What is generator?

100

Converts Electrical energy into Mechanical energy.

what is DC Motor?

200

Magnitude of current remains same w.r.t. time.

Magnitude of current changes w.r.t. time

what is Direct current?

what is Alternating current?

200

one end of resistor connected to one common point and another end of resistor connected to another common point.

what id Parallel circuit?

200

Mutual Induction.

when the current changes uniformly in one coil then emf induced in another coil.

what is working Principle of Transformer? explain

200

Faradays law of electromagnetic induction.

what is working principle of Generator?

200

When ever the current carrying conductor placed in magnetic field it experience the force.

What is working principle of DC Motor?

300

In AC frequency will be there but in DC no frequency.

Polarity will be there in DC but no Polarity in DC.

Only resistor will be connected in DC circuit but in AC resistor, inductor and capacitor will be connected in circuit.

Difference between AC & DC.

300

In parallel circuit voltage will remains same and  currents divides.

 In Series circuit current will remains same and  voltage divides

what about voltage and current in series and parallel circuit?
