Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
What else can I help you with?
What is he definition of electrical current?
The current flowing in an electrical circuit.
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.
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.
Does neutral carry current in an electrical circuit?
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.
Does the neutral wire carry current in an electrical circuit?
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.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
