What is meant by the term frequency of an alternating current? What is the value in India? Why is an alternating current considered to be advantageous over direct current for long range transmission of electric energy?
Frequency of Alternating current is equal to the number of cycles completed in one second.A current that varies its size and polarity at regular intervals is known as alternating current. In other terms, it is an electrical current that changes or reverses its direction on a regular basis, as opposed to Direct Current (DC), which always runs in one direction. A sine wave is a waveform that represents alternating electricity. The electric cycles are depicted by these curved lines, which are measured in seconds. The Hertz or HzHz unit is used to measure. alternating current or AC. In 1832, Michael Faraday used a Dynamo Electric Generator to conduct the first test on electric current based on his theories. In India, frequency of AC is 50Hz50Hz , i.e. 50 cycles per second.When compared to direct current, alternating current is regarded to be more advantageous for long-distance transmission of electric energy since it can be transmitted over long distances to distant locations with little loss of electric power.
