인덕터와 커패시터 Inductor and Capacitor 2

Inductor and Capacitor 2

Run High frequency alternating currents are difficult to pass through the inductor. An inductor is a part made by winding a wire. In the case of direct current, the inductor only works as a lead. When an AC voltage is…

Inductor and Capacitor

Run   Switch Why does the current gradually increase in the inductor? When a current starts to flow in the inductor, a magnetic field is generated around the inductor at the same time. This change in magnetic field induces electromagnetic…
