Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pulls only parallel to its length; thus, a force carried by a flexible connector is a tension with direction parallel to the connector.
Plugs and Wires. In the UK, electrical appliances connect to the mains using a three-pin plug. Each pin is connected to a wire with a unique colour, making it easy to identify. The features of a plug are shown below. Each wire, made of copper, is designed to conduct electricity.
Electrical resistance is the hindrance to the flow of charge through an electric circuit. The amount of resistance in a wire depends upon the material the wire is made of, the length of the wire, and the cross-sectional area of the wire.
A plug connects a device to the mains electricity supply. The cable between the device and the three-pin plug contains three copper wires that are coated with plastic. copper...

Everyone connects to the mains when plugging in an appliance such as a phone charger or kettle. Mains electricity is an alternating current (a.c.) supply.
15 Δεκ 2020 · What is Tension. The tension or tension force is a force experienced by a rope, string, or cable when it is pulled from the opposite end. It acts along the length of the wire and is equal and opposite to the applied force, that is, the force with which it is pulled.
A plug connects a device to the mains electricity supply. The cable between the device and the three-pin plug contains three copper wires that are coated with plastic.
