Electric current is the flow of electric charge through a closed circuit. It is generated by a power source, such as a battery or generator, and flows through conductive materials, like wires, to power electrical devices. The flow of current is driven by the difference in electric potential, or voltage, between the positive and negative terminals of the power source.

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.
How do resistors work and what is their role in an electrical circuit?
Resistors are electronic components that limit the flow of electric current in a circuit. They work by converting electrical energy into heat. Their role in an electrical circuit is to control the amount of current flowing through different parts of the circuit, helping to regulate voltage levels and protect sensitive components from damage.
How do resistors work in an electrical circuit?
Resistors work in an electrical circuit by limiting the flow of electric current. They are designed to resist the flow of electricity, which helps control the amount of current passing through a circuit. This resistance is measured in ohms and can be adjusted by changing the value of the resistor.
Do resistors limit current or voltage in an electrical circuit?
Resistors limit the flow of current in an electrical circuit.
What does current do in an electrical circuit?
Current is the flow of electric charge in an electrical circuit, carrying energy from a power source to the components in the circuit.
What is he definition of electrical current?
The current flowing in an electrical circuit.

Current is the flow of electric charge in an electrical circuit, carrying energy from a power source to the components in the circuit.
Can the current be negative in an electrical circuit?
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
Does a neutral wire carry current in an electrical circuit?
Yes, a neutral wire carries current in an electrical circuit.
Do resistors reduce current or voltage in an electrical circuit?
Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
How are electrical current and circuits related?
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
