An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
The current flowing in an electrical circuit.
Resistors limit the flow of current 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.
All the components in a circuit have a potential effect on the total current used by the circuit. You have to be more specific to get a more precise answer.
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
Yes, a neutral wire carries current in an electrical circuit.
Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.
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.
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.
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
No, neutral does not carry current in an electrical circuit. It is used as a return path for current to flow back to the source.
Yes, the neutral wire carries current in an electrical circuit, but it is designed to carry the current back to the power source to complete the circuit.
