This wiring method is used in cars and other vehicles because it saves the need to use expensive copper wires for the ground return side of several circuits in the car, such as tail lights, stop lights, rear windscreen wiper, etc.
ASE certified mechanic's answer
Most vehicles use the ground or body of the car for return paths. It is not considered a bad practice as it is done almost exclusively for vehicles as it saves wiring. More and more vehicles are using computer controls that utilize grounds to operate accessories. The most common application is a door switch that turns on a dome or courtesy light. When the switch closes (door open), it grounds the wire to the body and because the computer senses the wire grounded, it turns on the courtesy or dome light via a relay.
If you look at the negative post of a vehicle you can follow it to the body, chassis and engine grounds to prove they still utilize the body and chassis of the car for the ground return.
What else can I help you with?
Using the body of the car as a return path for current flow?
reduces the amount of wires needed.
What will happen without a neutral wire?
Current needs a return path to earth to flow. The neutral carries this flow. Therefore, no neutral and no current flow.
Does neutral carry current in an electrical circuit?
No, neutral does not carry current in an electrical circuit. It is used as a return path for current to flow back to the source.
How does a inductor or capacitor returns power to circuit?
A: Current flow only if there is a return path to the source it does not matter what it is connected to. What leaves at one end of the source will be identical to the return in current
Does the grounded conductor have normal circit current flow?
Yes, the grounded conductor carries normal circuit current flow in a typical electrical system. It provides a return path for current back to the source, completing the circuit.
Using the body of a car as a return path for current flow?
Practically all cars uses the chassis as return to the battery. It makes sense it eliminates wiring and at the same time it is more reliable as connection as opposed to have a return wire for every sensor lights whatever
What does the neutral wire do in an electrical circuit?
The neutral wire in an electrical circuit provides a return path for the current to flow back to the power source. It helps balance the electrical load and ensures the safety of the circuit by providing a path for excess current to return to the source.
High voltage by itself does not produce electric shock What does?
Electric shock occurs when high voltage passes through a person's body, typically when they provide a path for the electrical current to flow, such as through their hand or foot. The severity of the shock depends on factors such as the amount of current and the path it takes through the body.
Do neutral wires carry current in an electrical circuit?
No, neutral wires do not carry current in an electrical circuit. They are used to complete the circuit and provide a return path for the current to flow back to the source.
Does current flow through a circuit by taking the path of least resistance?
No, current does not flow through a circuit by taking the path of least resistance. Instead, current flows through all available paths in a circuit, with the amount of current in each path determined by the resistance of that path.
When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
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:)
