Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is applied to the inductor, causing current from the battery's positive terminal to flow down through the inductor and resistor. The increase in current causes a back EMF (… WebThe flyback transformer circuit was invented as a means of controlling the horizontal movement of the electron beam in a cathode ray tube (CRT).
