The current does work (W) on the wire, causing its internal energy (U) to increase. This, in turn, raises the temperature of the wire above its surroundings, so heat transfer (Q) takes place away from the wire. This is summarised as follows:
(W - Q) = U = m c (Tf - Ti)where:
W = work (joules)
Q = heat (joules)
m = mass of wire (kilograms)
c = specific heat capacity of wire (joules per kilogram kelvin)
Tf = final temperature (kelvin)
Ti = initial temperature (kelvin)
What else can I help you with?
What type of energy is created when moving a magnet through a coil of wires?
The type of energy created is electrical energy. As the magnet moves through the coil of wires, it induces an electric current to flow through the wires, generating electrical energy.
What happens to the electrical energy when power is transmitted through long distances?
Because wires are not perfect conductors, energy is released as heat. This is why electricity is transmitted at very high voltage and low current to reduce energy loss.
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
Does electrical energy travel through wires?
An electrical current - and the energy it carries - can travel through any conductor. Quite often, these conductors will be wires.
Why do wires turn hot in a circut?
Wires turn hot in a circuit due to the resistance they provide to the flow of electric current. This resistance causes energy to be converted into heat as the current passes through the wire. The higher the current flowing through the wire, the more heat is generated.
What causes wires to get hot?
Wires get hot when electrical current flows through them, causing resistance in the wire. This resistance converts electrical energy into heat energy, making the wire hot.
What kind of energy transforms an electric blanket from electrical energy to?
The energy transforms from electrical energy to heat energy in an electric blanket. When the electric current flows through the wires in the blanket, resistance in the wires produces heat, which warms the blanket.
What happens when a coil of wires moves through a magnetic field?
When a coil of wires moves through a magnetic field, an electric current is induced in the wires through electromagnetic induction. This phenomenon is known as Faraday's law of electromagnetic induction. The direction and magnitude of the induced current depend on the speed and direction of the coil's motion through the magnetic field.
What are the tiny particles that move through wires when a current flows?
The tiny particles that move through wires when a current flows are called electrons. These negatively charged particles carry the energy and information needed for electrical devices to function.
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
Why do wires heat up when a current flows in them?
Wires heat up when a current flows through them due to the resistance of the wire. As electrons move through the wire, they collide with atoms in the material, creating heat energy. This phenomenon is known as Joule heating.
Toaster turns from what energy to what?
A toaster turns electrical energy to heat and light energy by running the current through wires that begin to glow and release heat. ~Numos
