Question

The frequency of AC supply line in houses in England is:

Answer 1

AC stands for alternating current and for the ease of transmission and low cost and as it is easier to convert to DC, i.e. Direct current. AC power is preferred over DC power for supply to homes. The frequency of the AC supply line should be such that it satisfies easy, safe and efficient transmission.

Complete answer:
We know that alternating current (AC) flows one way, then other way, continually reversing direction. An AC voltage is continuously changing between positive and negative. The rate of changing the direction is called the frequency of the AC and it is measured in Hertz (Hz) which is the number of the forwards – backwards cycles per second.
An AC supply is suitable for powering some devices such as lamps and heaters but almost all electronics circuits require a steady DC supply for the easier and faster process of the transmission and also for low costs. An AC power is preferred to homes. AC supply is easy to convert into DC. AC power unit consists of step down transformers on the electric poles, which step down the AC voltage from the transmission time to normal AC voltage of 240V for home supply.
Power stations usually provide an alternating current (AC). In England the mains electrical supply is generated at a frequency of 50Hz and is delivered to houses at about 230 volts. Therefore, in England the frequency of AC supply lines in houses is 50Hz.

Additional information:
In the nineteenth century when AC systems started to grow rapidly, we lacked power electronics technology and also did not have a strong focus on renewable energy and energy storage systems. This is the main point why AC became so popular. It is very important to transmit the generated power in a high voltage and distribute it at lower voltage.

Note:
Mains electricity is the general purpose alternating current (AC) electric power supply. It is in the form of electrical power and that can be delivered to homes and businesses. The consumers use this power when they plug items such as domestic appliances, televisions and electric lamps. Mostly a frequency of 50Hz of AC supply is used in countries.
