How do you produce a current in a circuit without a voltage source?
A: mathematically speaking at zero potential with an infinite current source there should be current. PARADOX go around the world except go half way stop divide the distance and so forth mathematically there is going to be no end to the travel. ANSWER: Current will only flow if it find a path to flow. POTENTIAL for volts can exist without current flow. As soon as we try to measure it current will flow.
Why stop button always have NC contact?
When the contacts are Normally Closed (NC) the stop button is "in series" with the supply voltage. By activating the STOP function the contacts open interrupting the flow of current.
How is a resistor different from a fuse?
A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.
What is the difference between a series electric circuit?
A series circuit is a circuit that only has one path for current to flow on, a parallel circuit is a circuit that has multiple paths for current to flow on. Parallel circuits are mostly used, especially in your house/home. The reason of that is because, if a device in a series circuit electrically malfuctions or goes down, it will stop the current flow, thus ending and cuting the whole rest of the circuit. In a Parallel circuit, if a device electrically goes down, current will still be able to flow through the other circuit branches, and the rest of the circuit, thus keeping electricity flowing.
What happens to lights in parallel if one goes out?
In a series circuit each light completes its part of the circuit and connects to the next light. So, if one light fails, the circuit is broken and the flow of current to all lights must stop.
How do you start and stop the flow of electric current?
with a switch.
What cuts down the flow of current but does not stop it?

An object that will stop the flow of a current is called a switch.

How do insulators stop the current to flow through them?
they lack free electrons
What is a material that cuts down the flow of current but does not stop?
That is an electrical resistor.

What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
How can you break a circuit?
To open a circuit (stop the flow of current), typically a switch is used.
Why was a switch made?
A switches main purposes is to stop the current flow in a closed circuit.
What could stop the flow if there is too much electric current?
circuit breaker or fuse
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
