Define Variable Current ?
Answers
Answer:
An example of a 'variable' electric current would be the current that flows through the earbuds that you listen to, or through the speaker in car radio or your tv. This current alternates back and forth but not as regularly as 'AC' currents do.
Answer:
Various countries' mains conditions are simulated using a variable current and voltage regulator. Additionally, it is utilised to check the frequency response of power equipment, frequency relays, and other parts.
Explanation:
Despite being frequently referred to as "variable," the mains current is not the same as the alternating current. Variable current is any sort of current that varies not just periodically but also erratically, in contrast to alternating current, which changes both its direction and amplitude over time.
Additionally, it is utilised to check the frequency response of power equipment, frequency relays, and other parts. Current transformers are checked using sources with variable current and variable frequency.
