Charge Conservation
In the serial circuit, The current is the same everywhere. In the parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of … more
Electricity & Magnetism Simulation
Electroscope
Electroscope Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the (+) charged body is close to the metal plate, the metal foil’s free electrons are attracted to the metal plate, … more
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, an insulated conductor develops … more
Electrostatic induction (the viewpoint of metal bonding)
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, an insulated conductor develops … more
Conductor and Insulator
What happens when the charged body is close to the conductor and insulator? ConductorElectrostatic induction is a redistribution of electrical charge in an object caused by nearby charges’ influence. In the presence of a charged body, an insulated conductor develops … more
Electromagnetic Waves around of Visible Rays
Electromagnetic radiation refers to the electromagnetic field waves radiating through space-time, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Types of Electromagnetic Wave Electromagnetic waves are classified based on the length … more
Resistance Connection
Resistance is analogous to a toll-gate, meaning that it limits the flow of current. Please note that excessive analogy may cause misconceptions. (The cars in the simulation are crowded out, but the actual charges are evenly distributed throughout the conductors.) … more
Magnetic Field around a Circular Wire
The magnetic field is the area surrounding a magnet in which the magnetic force exists. The magnetic field is also formed around the conductor through which the current flows. This is electromagnetism. The direction of the magnetic field can be … more
Magnetic Field around a Wire
You can drag the compass. The magnetic field is the area surrounding a magnet in which the magnetic force exists. The magnetic field is also formed around the conductor through which the current flows. This is electromagnetism. The direction of … more
Electric Potential 3
What is the voltage value of the voltmeter? Voltage distribution in series connection When two or more resistors are connected in series, the sum of the resistors’ voltages becomes the total voltage. Therefore, the resistors divide the supplied voltage according … more
Electric Potential 2
Battery and Load In an electrical circuit, the battery maintains a voltage difference to allow current to flow through the circuit. In an electric circuit, the place where energy is consumed is called a load. Generally, in school labs, the … more
