# Question: Which Side Is Positive On A Toggle Switch?

## What happens if you reverse hot and neutral wires?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet.

Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.

This wire is commonly referred to as the neutral wire, and it should always be white..

## How does the position of the switch affect the current?

A switch interrupts the flow of current in a circuit. Think of a light switch on the wall. Concept is exactly what you want to achieve. So, the switch interupts current by stopping flow to the load.

## What happens if you switch positive and negative wires?

Reversing the polarity in a circuit can ruin the power source or even cause an explosion. Connecting the wrong wires, like using a positive wire when it should be a negative wire, can also fry the wires themselves. Never use an analog multimeter if you aren’t sure which wire is positive vs. negative.

## Which wire is hot if both are black?

The black wire is the “hot” wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel.

## What are the 3 requirements of a circuit?

A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. Circuits are driven by flows.

## Should a switch be on the positive or negative side?

This covers AC power and positive ground circuits as well as negative ground. The circuit works the same no matter where you put the switch. Part of the electrical code (for house wiring) says that the switch should always go between the hot conductor and the load. This is for safety.

## Which side of the switch is hot?

A single-pole switch has two brass terminal screws on the side that receive the black (“hot”) wires of the circuit. One black wire comes from the power source and the other goes to the light(s).

## Which side goes on the positive side of the circuit?

A battery has two sides, the negative side is the low voltage, measuring in at 0v, the positive side is the high voltage, measuring in at 1.5v. Energy will always want to flow out of the positive side of the battery to get to the negative side to find balance.

## Should switch be on live or neutral?

Live is… live. A connection from neutral to ground will not likely kill you, but a connection from live to ground stands a decent chance of doing so. And more of the circuit is live than neutral if you switch only the neutral, including any electrical devices on the circuit.

## What happens if I wire a light switch wrong?

You could put the switch on the neutral wire and everything would work, but it would leave voltage potential to ground in the light when it is switched off. That makes it a bit hazardous for changing light bulbs. If you became an electrical path to ground through a wet floor or something you could get a shock.

## Why are there 2 black wires on light switch?

The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault. In most cases, two black wires will be attached to the switch’s two terminal screws.

## Does it matter which way you wire a switch?

If your switch has a “LINE” marking, the always hot wire goes to this. The other connection will be “LOAD” where the load (ie light fixture) is wired. The load wire may have red electrical tape on it to differentiate.

## Does it matter which wire goes where on a lamp?

Hot and Neutral Electrical Paths in a Lamp Switch and Socket The neutral path should run from the wide prong at the wall outlet through a marked (insulation) wire to the neutral terminal on the switch and to the threaded metal bulb socket.

## What happens if you switch line and load wires?

Here’s what happens when somebody wires a GFCI receptacle with the load and line wires reversed: The GFCI will work, in the sense that you can plug in a hair dryer and the hair dryer will blow hot air. … If the load and line wiring gets messed up, a ground fault (radio in the tub) won’t trip the GFCI.

## Which circuit will run down the battery first?

Remember that each of the parallel bulbs are as bright as the single bulb. So the two bulbs in parallel demand energy from the battery twice as quickly as one alone. That’s why the parallel circuit runs down first.
