Which device controls the flow of electrons in an electric circuit?
Flow of electricity in a circuit is controlled by using 'resistor'.
Will a circuit work without a switch?
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
When we 'switch on an electrical appliance' what change are we making to the circuit?
By 'switching on an electrical appliance' we are completing (closing) the electrical circuit, allowing electricity to flow and the device to work.
What safety devices provides a weak link in a circuit that will melt if it received too much current thus breaking the circuit and stopping the flow of electricity?
The device that has a melting link in it is called a fuse.
What best describes electric circuit?
An electric circuit is best described as a loop. the flow of electrons
What is the Device in a circuit to make it harder for electricity to flow?
the device is a resistor
What is a device that resists the flow of electricity in a circuit?
A resistor.
Which device controls the flow of electrons in an electric circuit?

Will a circuit work without a switch?
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
When does electricity flow?
When there is a closed circuit, there is electricity flow.
When does electricity start to flow?
When the electrical circuit is completed - usually by closing a switch.
What the advantages of active and passive device?
An active device is any type of circuit component with the ability to electrically control electron flow (electricity controlling electricity). In order for a circuit to be properly called electronic, it must contain at least one active device
Why is an electricity not flow in an open circuit?
The electricity will flow from higher potential to lower potential in a closed circuit.
How does a switch control the flow of electricity?
When the switch is open, the circuit is not a complete circuit. Electricity needs a complete circuit of conductive material. The switch breaks the circuit causing the flow of electricity to be disrupted. When you close the switch, a full circuit is restored thus restoring the flow of electricity.
When we 'switch on an electrical appliance' what change are we making to the circuit?
By 'switching on an electrical appliance' we are completing (closing) the electrical circuit, allowing electricity to flow and the device to work.
A path for electricity to flow is a?
Circuit
