Can a wire be called a resistor? Also do all circuits require a resistor? If no then give an example of a circuit which doesn't have a resistor. Please thanks

In most cases, wires have resistance. Some resistors are basically wires. Sometimes the resistance provided wires is important to the function of the circuit - in which case you would expect them to be in the circuit diagram.Additya said:Can a wire be called a resistor?

Talk to an Electrical Power Engineer. Despite the fact that their 'wires' tend to be very thick, they are also very long and their resistance accounts for a significant proportion of your Electricity Bill.Additya said:Can a wire be called a resistor?

A resistor is an electronic component that is used to restrict the flow of electric current in a circuit.
Resistors are used to control the flow of electric current in a circuit. They can be used to limit the amount of current or to create specific voltage levels.
Technically, a wire can have some resistance, but it is not designed to be a resistor. In most cases, a wire is used to connect components in a circuit and has a very low resistance compared to a resistor.
Resistors work by converting electrical energy into heat. This is done by creating a barrier to the flow of electrons in a circuit, which results in a voltage drop.
The unit of measurement for resistance is ohms (Ω). This represents the amount of resistance in a circuit that will result in a one-ampere current for a one-volt potential difference.
