When a device is removed from an outlet box which wire must be connected in such a way that it maintains continuity?
All three wires, the "hot", neutral and the ground must all maintain the integrity of the circuit. This is why pigtails are connected from the main circuitry to the receptacle or switch devices so that they can be removed without opening the electrical circuit.
Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
Can electric circuit b completed without earth?
Yes, an electric circuit can be completed without connecting it to earth. The circuit needs a complete path for the current to flow back to the source, so as long as the circuit is properly connected and the electrons can flow through the components, it will work without needing an earth connection.
What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
Will a circuit work without a switch?
Yes, a circuit can work without a switch if it is designed to be always on or if the components are connected directly without the need for a switch to control the flow of current. However, in many applications, a switch is necessary to control when the circuit is on or off.

Why is a voltmeter connected in parallel in an electrical circuit?
A voltmeter is connected in parallel in an electrical circuit to measure the voltage across a specific component or part of the circuit without affecting the flow of current through the circuit.
Why is a voltmeter connected in parallel?
A voltmeter is connected in parallel because it measures the voltage across a component or circuit without affecting the flow of current through it. This allows for an accurate reading of the voltage without disrupting the circuit's operation.
Why are voltmeters connected in parallel?
Voltmeters are connected in parallel because they are designed to measure the voltage across a specific component or part of a circuit without affecting the overall current flow in the circuit. Connecting them in parallel ensures that they measure the voltage accurately without altering the circuit's behavior.
What is the name of a series circuit?
An electric circuit connected so that current passes through each circuit element in turn without branching.
Can the car run without the negative terminal connected?
The negative teminal needs to be connected to complete the electrical circuit. Without that none of the electronics in the vehicle will work, including the starter.
What is it called when Appliances without plugs or are connected directly to a circuit are said to be?
That is called Hard wired

Can a fridge and microwave be safely connected to the same circuit"?
Yes, a fridge and microwave can be safely connected to the same circuit as long as the circuit can handle the combined electrical load of both appliances without exceeding its capacity. It is important to consult with a qualified electrician to ensure proper installation and safety precautions are taken.

How must voltmeters be connected in a circuit?
Voltmeters must be connected in parallel with the component or section of the circuit where the voltage is to be measured. This parallel connection allows the voltmeter to measure the potential difference across the component without significantly affecting the circuit's operation. It is important to ensure that the voltmeter has a high internal resistance to minimize the current flowing through it and avoid altering the circuit behavior.
