Electromagnetic induction Moving a magnet around a coil changes the magnetic field inside the coil, which causes current to flow through the coil. This phenomenon is called ‘electromagnetic induction’; the current flowing through the coil is ‘induced current.’ The result...
Build the indoor wiring to make the electric appliance work. Home wiring All electrical devices have a resistance value, and this resistor limits electric current. A power strip or indoor wiring is a parallel connection of resistors also. The electrical...
Electromagnetic induction Moving the magnet around the inductor will change the inductor’s magnetic field, which will cause the current to flow through the inductor. This phenomenon is called electromagnetic induction. The current flowing in the inductor is called the induced...
2022.12.24 Update: We made that the magnetic field line between the magnets connected smoothly. Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When...
Resistance Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and allow current to flow...
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the mouse. * In the...
Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate the switch after fully...
Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. The capacitor is made...
Half Adder An adder is a logic circuit that can perform additional operations on binary numbers. It can be composed of only three types of logic circuits: AND, OR, and NOT gates. Bit addition is handled with an XOR gate...
Logic Gate Logic circuits are responsible for arithmetic operations in a computer. All numbers are converted to binary for the logic circuit to work. A binary number is a number system that consists only of the numbers ‘1’ and ‘0’....
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 was thought to flow...
When you rub a balloon on a cat, it charged. Charged balloons can be attached to walls or cat. The charged balloon rolls down as it discharges after a certain period of time. Triboelectricity If you peel off a thin...
