A resistor in an electrical circuit is used to control the flow of electric current and reduce the amount of voltage in the circuit. It helps regulate the amount of current that flows through the circuit and protects other components from damage due to excessive current.

Does a resistor reduce current or voltage in an electrical circuit?

A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.


What do a resistor do in a circuit?

A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.

How does a resistor reduce voltage in an electrical circuit?

A resistor reduces voltage in an electrical circuit by converting some of the electrical energy into heat. This process slows down the flow of electricity, resulting in a decrease in voltage across the resistor.


What component in an electrical circuit provides resistance?

The component in an electrical circuit that provides resistance is called a resistor.


How does a resistor affect the flow of current in an electrical circuit?

A resistor restricts the flow of current in an electrical circuit by resisting the flow of electrons. This causes a decrease in the amount of current that can pass through the circuit.


When they can use a resistor in a circuit?

When the circuit needs the electrical property of resistance, of course.


What is a resistor What does it do in a circuit?

A resistor is a passive two-terminal electrical component that limits the current flowing in electrical or electronic circuits.


How does a resistor reduce current in an electrical circuit?

A resistor reduces current in an electrical circuit by impeding the flow of electrons, causing them to encounter resistance and slow down as they pass through the resistor. This restriction in flow results in a decrease in the overall current in the circuit.


How does a resistor limit current or voltage in an electrical circuit?

A resistor limits current in an electrical circuit by impeding the flow of electrons, which reduces the amount of current passing through it. This, in turn, helps regulate the voltage in the circuit by creating a drop in voltage across the resistor.


How does a resistor work in a circuit to regulate the flow of electrical current?

A resistor in a circuit works by impeding the flow of electrical current, which helps regulate the amount of current passing through the circuit. This is achieved by converting electrical energy into heat energy as the current passes through the resistor, limiting the flow of electricity.


Is a battery a resistor if not what is?

No, a battery is not a resistor. A battery provides electrical energy, while a resistor is a component that restricts the flow of current in a circuit.
