Electricity can be defined as the flow of negatively charge particles, called electrons. This flow is only possible in conductors (ex. metals) but not in insulators (ex. glass).
As the electrons flow, they have to overcome frictional forces. Friction produces heat.
The more friction that is encountered, the more heat is generated. So the current passes quite easily through the copper conductors, generating very little heat. As it reaches the load (heater, lamp etc), the resistance is greater so the bulk of the heat is generated here.
Electrical energy is being converted to thermal energy.
What else can I help you with?
What is a closed path through which current can flow?
A closed path through which a current can flow is called a circuit. Electric Circuit:)
What is the evidence that an electrical circuit is closed?
When that circuit has no breaks. It is an endless path of current flow.
The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
What is a single path for electric current to flow through?
is called an electrical circuit
How do fuses and circuit breakers protect you home against electrical fires?
It must understand that, short circuit is the case when the electricity find a lower resistance path to travel through. It will result to large amount of electricity flow and with high current flow then it emitted heat and would be so hot that it start the fire. Preventing short circuit damage, it install the fuse or circuit breaker as the bottle neck. When too much of the current flow through then the circuit breaker stop the flow of current and prevent fire.
What is the electric force that makes current flow in a circuit is related to is?
The electric force that makes current flow in a circuit is related to the resistance.
The electric force that makes current flow in a circuit is related to the what?
The electric force that makes current flow in a circuit is related to the resistance.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
Why must a circuit be closed in order for current to a flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
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.
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.
What is a circuit with two or more branches for current to flow called?
Parallel circuit
What is a closed path through which current can flow?
A closed path through which a current can flow is called a circuit. Electric Circuit:)
What is the name for the status of a circuit that has breaks which electric current that cant flow?
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
A wire wrapped around a magnet is an example of a open circuit?
No, a wire wrapped around a magnet is an example of a closed circuit, as the wire forms a continuous loop for the flow of electric current. An open circuit is a circuit that is interrupted, preventing the flow of current.
