Pranav Jha said:hey guys, i just started learning about tuned circuits. However, i can't understand the difference between line current and oscillating current and the reason for their different magnitudes in a parallel resonant LC circuit.
Please clarify the difference between the two.

Line current refers to the flow of electricity through a conductor in a constant direction, typically from a power source to a load. Oscillating current, also known as alternating current, changes direction periodically, usually at a fixed frequency.
Line current is used to power most household and industrial appliances, while oscillating current is used for devices that require a changing magnetic field, such as motors and generators. Oscillating current is also more efficient for long-distance transmission of electricity.
Line current is typically generated by a power plant through the conversion of mechanical energy into electrical energy. Oscillating current is produced by using a device called an alternator, which rotates a coil of wire within a magnetic field to generate a changing current.
Line current is measured in amperes (A), which is a unit of electrical current. Oscillating current is measured in root mean square (RMS) amperes, which takes into account the changing direction of the current.
Yes, line current and oscillating current can be used together in certain applications, such as in a transformer. The transformer can convert oscillating current to line current for use in household appliances and electrical equipment.
