Chapter 10 – Electric Current and Its Effects
- The flow of electrons across a conductor is known as electric current.
- The use of symbols to represent electric components is convenient. A circuit diagram can be used to represent an electric circuit using these.
- When an electric current is passed via a wire, it heats up. It’s the current’s heating impact. This effect can be used in a variety of ways.
- When enormous electric currents are pushed through wires constructed of specific materials, they melt quickly and shatter. Electric fuses, which prevent fires and damage to electrical appliances, are made from these materials.
- One cell’s positive terminal is connected to the following cell’s negative terminal. A battery is a collection of two or more cells in this configuration.
- A wire acts like a magnet when an electric current travels through it.
- A full path for the flow of electric current is referred to as an electric circuit.
- Components of an Electric Circuit: The following are components of an electric circuit:
I. Cell: A cell is a device that provides energy to allow current to flow.
II. Bulb: When an electric current passes through it, it illuminates.
III. Switch: Turns on or off the circuit.
IV. Connecting Wires: These wires assist in the conduct of electric current and the completion of the circuit.
Electric Current’s Effects:
I. Heating Effect: When an electric current runs through a wire, it heats up. This is the electric current’s heating impact. When current travels through an electric heater, a coil of wire called the element gets red hot. The quantity of heat generated by a wire is determined by the material, length, and thickness of the wire.
II. Fuse: A fuse is a safety device that protects an electric circuit from harm. A small wire is inserted into porcelain or insulating material to create it.
III. MCB: The abbreviation MCB stands for Miniature Circuit Breakers. When the current in a circuit reaches the safe limit, these switches automatically turn off.
- Magnetic effect occurs when an electric current travels across a wire. This is the electric current’s magnetic effect. Hans Christian Oersted was the first to notice this.
- An electromagnet is a current-carrying coil of insulated wire wound around a piece of iron. It is a wire coil wound on a soft iron core that is used to separate magnetic material from garbage. Small electromagnets are used by doctors to remove small bits of magnetic material that have accidentally fallen into the eye. Electromagnets are also found in many toys.
