Question

How is the working of an electric bell affected if alternating be current is used instead of Direct current?

Answer 1

Hint: We all know, nearly all electrical devices work by AC. The reason behind it is that when the power is discharged from the powerhouse to homes via transmission cables, then it is in-variable form, and we can easily adjust the input current at homes at low or high levels according to the rating of the appliance that we are using.

Complete step by step answer:
We have seen that an electric bell comprises many components. The components are mainly an electromagnet made up of spiral coils wrapped up over a metal rod, and a small metal hammer is used to hit the ball. When we pass the coils' charge, the magnetic field is generated around the rod, and it attracts the hammer attached to the clip, which hits the bell, and we get the required sound.
The electrical bells run the same on both AC and DC currents. The two AC and DC currents do the same process of initiating the electromagnet, and the bell works. Still, the only difference is that in the case of AC, the electromagnet's polarity is switching continuously, but this does not affect the bell.

Therefore, the running of the electric bell is not affected, whether we use AC or DC.

Note:
As we all know that in the case of direct current, the average value of the intensity of current and the maximum value of current is the same, but in the case of AC, the average value and the maximum value of the current is different.
