Same as the coil used in the previous notes. The Inductor is a coiled conductor usually a copper wire. From the circuit below, an Inductor is connected across a DC voltage source. The current flows across the Inductor coil, and a Magnetic field is generated around the Coil.
DC Supply
DC is straight forward. In a DC power supply, the current flow only in one direction, between negative Cathode to positive Anode. When any load (like a resistor or an LED) is connected across a battery, the current flows through the load and the load uses the current flow. In case of a resistor heat energy is released. For an LED light is emitted.
