Why is it necessary to have a closed circut to have a complete transfer of energy?

A closed circuit ensures that there is a continuous path for the flow of electrons, allowing a complete transfer of energy. When the circuit is open, there is no complete path for the energy to flow, resulting in a disruption of the transfer process.


When a current is stopped at any the whole circuit becomes open what current is that?

An open circuit has no current ( 0 amperes ).


What is through a discontinuous circuit which no current can flow?

meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)


What are the effects of an open circuit?

In an open circuit, there is a break in the circuit path, preventing current flow. This results in no electrical current passing through the circuit and no electrical energy being transferred. As a result, any components or devices connected to the circuit will not function.


Why is it necessary to have a close circuit too have a complete transfer of energy?

A closed circuit is necessary for a complete transfer of energy because it allows for the flow of electrons from the energy source to the load and then back to the source. If the circuit is open, the flow of electrons is interrupted, and energy cannot be transferred effectively. Closing the circuit completes the pathway for the energy to move along.


A loop with a break in it that prevents current from flowing is called?

an open circuit.


In a series circuit if 1 bulb goes out the circuit is considered open or closed?

If one bulb in a series circuit goes out, then current can't flow anywherein the circuit. A circuit in which current can't flow is an open circuit.


What determines if a circuit is open or closed?

A circuit is considered open if there is a gap in the path for electricity to flow, causing the current to stop. A circuit is closed when there is a complete, unbroken path for the electrical current to travel through.


What is a break in an electrical circuit called?

A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.


An open circuit is one that has aan?

An open circuit is a break in the conductive path of the circuit,thus stopping current flow.


Why current source is replaced by open circuit across the terminals?

For an ideal current source, this means replace the current source with an open circuit. Resistance can then be calculated across the terminals.


What device used to open a circuit if too much current flows through it?

A circuit breaker is a device used to open a circuit if too much current flows through it.
