## What is an electric circuit answer?

Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.

## What does an electric circuit mean Ncert?

What does an electric circuit mean? Ans. A continuous conducting path consisting of wires and other resistances and a switch between the two terminals of a cell or a battery along which an electric current flow is called a circuit. Q2.

## What are the 3 components of an electric circuit?

Every circuit is comprised of three major components:a conductive “path,” such as wire, or printed etches on a circuit board;a “source” of electrical power, such as a battery or household wall outlet, and,a “load” that needs electrical power to operate, such as a lamp.

## What is an electric circuit explain with the help of diagram?

An electrical circuit is a path or line through which an electrical current flows. The path may be closed (joined at both ends), making it a loop. A closed circuit makes electrical current flow possible. It may also be an open circuit where the electron flow is cut short because the path is broken.

## What is the function of an electric bulb?

An electric bulb is a device which produces light when electricity is passed through its terminals. The bulb has two thick contact wires in the center with a thin wire attached between them. This thin wire is called filament.

## What is the purpose of a circuit diagram?

A drawing meant to depict what the physical arrangement of the wires and the components they connect is called “artwork” or “layout” or the “physical design.” Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.

## What’s a block diagram?

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams.

## How do you describe a circuit?

A circuit is a closed loop that electrons can travel in. A source of electricity, such as a battery, provides electrical energy in the circuit. Unless the circuit is complete, that is, making a full circle back to the electrical source, no electrons will move.

## Is wiring a diagram?

A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.

## What is the difference between a wiring diagram and a circuit diagram?

Wiring Diagram shows the actual practical connection between electrical appliances, components. Circuit Diagram just shows the simple connection between components it does not shows the practical connection.

## Is wiring a harness?

A cable harness, also known as a wire harness, wiring harness, cable assembly, wiring assembly or wiring loom, is an assembly of electrical cables or wires which transmit signals or electrical power.

## Is red or black live or neutral?

Black (neutral) Red (live) Green and yellow (earth)

## What happens if you mix up 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.

## What does the red wire mean?

Red wires are usually used as a secondary hot wire. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe. Green Wire: Ground. Green insulated wires are often used for grounding.

## Is red and black wiring legal?

Yes, sleeving conductors to identify them is acceptable. If it makes any difference all the other cables in the house are Red & Black.

## How old is black and red wiring?

PVC Black and Red cores – Between 10 and 40 years old. This is the “standard” cable known as twin and earth, but using colours that predate the harmonisation of colours in 2004, which was implemented in 2006.

## Does a 1970s house need rewiring?

The majority of 1970s houses do not need rewiring. They will probably just need a consumer unit and earthing upgrade. If you have a consumer unit change then the electrician will have to inspect a lot of the property anyway.

## Which color wires go together?

US AC power circuit wiring color codes The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.

## What if I have two black wires?

Having two black wires in a switch or light fixture just isn’t that uncommon and is not a sure sign of bad wiring. Step 1 Set your multimeter to measure voltage. Voltage is the pressure of electricity flowing through a wire, and a hot black wire carries the voltage.

## What color wires go to XYZ?

I normally use Green for ground, White for Neutral, Black for X, Red for Y (and orange for Z on an L21-30). On the Cal Standard plugs and connectors the X is colored Red and Y is colored Black.
