heat
AnswerThe answer is work, not heat.
'Heat' is the name given to energy in transit from a warmer body to a cooler body. So heat cannot be produced by electricity. Electricity does work on a conductor, causing its internal energy to rise which, in turn, causes its temperature to rise and this then results in heat transfer away from the conductor.
The heat generated by an electric current is in watts, Current x volts. So current alone is not enough to define it. By Ohms Law, Volts = Current x Resistance, so another way of expressing watts is (Current squared) x Resistance. If you know the current andthe resistance you can get the wattage, which will give you the heat generated.
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
Wherever there is resistance or conductance and a current generated through interaction of electrons and holes there will be amplification. Trans-resistor is basically transfer of resistance.
A: A photocell has the property to change resistance as photon hit its surface that cause a change in resistance with current is flowing a voltage is generated
The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
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.
Heat is generated when current flows through a material due to the resistance within the material. This relationship is described by Joule's Law, which states that the heat produced is directly proportional to the square of the current and the resistance of the material. In other words, the higher the current flowing through a material with resistance, the more heat is generated.
The starting current is high because when the motor is not rotating no back-emf is generated, leaving the starting current to be determined by the armature resistance, which should be low.
In resistance welding, the heat for fusion is generated by passing a high electrical current through the materials being welded. The resistance of the materials to the flow of electrical current causes them to heat up rapidly at the interface, melting and fusing together.
When the direction of current is reversed, the heating effect remains the same. The amount of heat generated is determined by the magnitude of the current and the resistance in the circuit, independent of the direction of the current flow.
Cooling a wire can increase its electrical resistance, which in turn can reduce the current flowing through the wire when connected to a power source. This reduction in current can lead to a weaker magnetic field generated by the electromagnet.
