Now, the direction of flow of electrons also varies with the movement of the magnetic field.ĪC can also be generated by placing a wire in the static magnetic field, but now the current carrying wire needs to be rotated. The current carrying wire is placed in rotating magnetic field.
Your answer lies in the generation of AC. You must be thinking what makes AC conduct bidirectionally. forward and backward it is called bidirectional current.ĪC is bidirectional Current. If electron flow in one direction, it is unidirectional current but if it flows in 2 directions, i.e. The current is the consequence of flow of electrons. Low Voltage applications in electronic circuitsĪC is the type of electric current in which polarity of the current does not remain constant. High Voltage application such as home appliances, office equipments. It can be resistive, inductive or capacitive.Ĭapacitor allows DC to pass thorugh it, thus capacitive impedance will be low.Ĭapacitor blocks DC, thus capacitive impedance will be infinite. Not suitable as power loss is directly proportional to distance.īetween 50 Hz to 60 Hz, different in different countriesīy placing current carrying coil in rotating magnetic field.īy placing current carrying coil in steady magnetic field. Suitable for long distance transmission as power losses are minimum. DC voltage is low-level voltage while AC is high-level voltage.ĪC is the type of electric current which varies instantaneously with time.ĭC is the type of electric current which remains constant with time. Another important difference between AC and DC is the magnitude of the voltage. AC and DC, both are the types of electric current but both contrast each other regarding generation, flow in circuit and applications.
