What are the questions that are asked at interview for electrician?

Common Electrician Interview Questions

  • Why did you become an electrician?
  • How many years have you been working in the industry?
  • How and where did you receive your training?
  • What was a time when you had a problem you could not figure out and you had to find a solution on your own?

What is basic of electrical?

The three primary forces in electricity are voltage, current flow and impedance (resistance). They are the fundamental forces that control every electrical circuit everywhere. Voltage is the force that pushes the current through electrical circuits.

What is AC DC current?

Electric current flows in two ways as an alternating current (AC) or direct current (DC). In alternating current, the current keeps switching directions periodically – forward and backward. While in the direct current it flows in a single direction steadily.

What is current and voltage?

Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field.

What are the most common interview questions?

Most Common Interview Questions:

  • Tell me something about yourself.
  • How did you hear about this position?
  • Why do you want to work here?
  • Why did you decide to apply for this position?
  • What is your greatest strength?
  • What are your strengths and weaknesses?
  • What do you know about this company/organization?

What is difference between electrical and electronics?

The term Electrical deals with the flow of electrical power or charge, whereas electronics deals with the flow of electrons. There is only a minute difference between electrical and electronics, and both of them more or less deal with electricity.

Why do you want this job?

Talk about specific examples of how you can help this company achieve their goals and highlight any relevant transferrable skills that will make you stand out as the right candidate. Write down any recent achievements you can talk about or any challenges you’ve faced recently that might be related to this new job.

What are the 3 types of power supply?

There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.

What are 3 types of electrical circuits?

Types of Electric Circuit- Closed circuits, open circuits, short circuits, series circuits, and parallel circuits are the five main types of electric circuits.

What are types of electricity?

There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.

What is the frequency of AC?

The frequency of Alternating Current in India is 50 Hz. This simply means that the magnetic field around the armature in the Ac-generators in India rotates 50 times per second.

Is battery DC or AC?


Batteries provide DC, which is generated from a chemical reaction inside of the battery.

What is the frequency of DC?

0 Hz

The frequency of direct current (DC) is 0 Hz, as the current only flows in one direction.

Are capacitors DC or AC?

Capacitor comes in different shapes and their value is measured in farad (F). Capacitors are used in both AC and DC systems (We will discuss it below).

Is DC a signal?

The terms AC and DC can describe signals as well. An AC signal is a current, voltage, or numerical sequence that consistently exhibits both positive and negative values, and a DC signal exhibits only positive values or only negative values.

How do you convert AC to DC?

AC to DC conversion. After Stepping down of voltage, AC is converted to DC using rectifiers. A full bridge rectifier can be used to convert AC to DC. In this device, 4 diodes are used which operates in forwarding bias and not in reverse bias.

Is inverter AC or DC?

A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).

How is DC current calculated?

P = V X I . Here P is power in watts. V is voltage in volts. I is current in amps.
