What do the following symbols represent in a circuit write one function of each?

In a circuit, common symbols include resistors, capacitors, and inductors. A resistor (represented by a zigzag line) limits current flow and dissipates energy as heat. A capacitor (depicted as two parallel lines) stores electrical energy temporarily and releases it when needed, helping to smooth out voltage fluctuations. An inductor (illustrated as a coiled wire) stores energy in a magnetic field when electrical current passes through it, often used for filtering and energy storage in power supplies.
