Electric Current, Conductor, Insulator

Electric voltage(Regions of a positive or negative charge, such as those at the terminals of a battery) force electrons through a conductor. Electrons that have negative charges can be moved around a circuit. Originally, the current … more

LED

The principle of LED

LED LEDs are electronic devices that emit photons. LEDs have higher efficiency and longer life than bulbs. Basically, LEDs have a structure like a p-n junction diode. The p-n junction diode is made by attaching a … more

Electrostatic Induction

Electrostatic Induction

What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, … more
