# What is a circuit diagram?

A circuit diagram (electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit.

What is the definition of schematic diagram?

A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.

What is reactance diagram?

The reactance diagram is the simplified equivalent circuit of power system in which the various components of power system are represented by their reactances. The reactance diagram can be obtained from impedance diagram if all the resistive components are neglected.

## What is a simple electric circuit?

An electric circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. The point where the electrons leave an electrical circuit is called the “return” or “earth ground”.

## What is the 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.

## What does it mean to be a closed circuit?

closed circuit. An electric circuit through which current can flow in an uninterrupted path. Compare open circuit. A television system in which the signal is usually sent by cable to a limited number of receivers.

## How does the circuit work?

An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move. When the electrons get to a device like a light bulb, your computer, or a refrigerator, they give it the power to make it work.

## Which way does the current flow in a circuit?

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

## What is an electric bell?

An electric bell is a mechanical bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing or clanging sound.

## What does current do in a parallel circuit?

A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.

## What is an electrical wiring diagram?

A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system.

## Why do you use symbols to draw a circuit diagram?

The idea of a circuit diagram is to use circuit symbols instead of drawing each component in the circuit. Always try to make the wires straight lines, and don’t be tempted to make them wiggly. If you have to draw wires to join circuit symbols that are already shown, use a ruler and don’t let the wires cross each other.

## What is the definition of schematic diagram?

A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension.

## What is an electrical 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 a series circuit in electricity?

Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur frequently. Components connected in series are connected along a single path, so the same current flows through all of the components.

## What are the electrical symbols?

An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit.

## What is series resistance?

Definition :- Imagine two or more resistors in series, i.e. connected one after another so that the same current flows through them. The total resistance of the collection is the sum of individual resistances.

## What is the Ohm’s law?

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the “resistance”, R. Ohm’s Law is given by: V = I R where V is the potential difference between two points which include a resistance R.

## What is equivalent series resistance?

Effective Series Resistance (or Equivalent Series Resistance or ESR) is the resistive component of a capacitor’s equivalent circuit. A capacitor can be modeled as an ideal capacitor in series with a resistor and an inductor. The resistor’s value is the ESR.

## What is the ripple current?

Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification.

## What is the cause of low ESR?

The ESR is decreased in polycythemia, hyperviscosity, sickle cell anemia, leukemia, low plasma protein (due to liver or kidney disease) and congestive heart failure. The basal ESR is slightly higher in females.

## What is a line diagram?

The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. A one-line diagram can also be used to show a high level view of conduit runs for a PLC control system.
