Electrical basic questions and answers

Electricity is the presence and flow of electric current. Using electricity, we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word "electricity" is sometimes used to mean "electrical energy".

What is DC or AC 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.

Why is a fuse used?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.

Who is the first electrical engineer?

Although it is impossible to precisely pinpoint a first electrical engineer, Francis Ronalds stands ahead of the field, who created a working electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity.

What is the basic of electrical engineering?

Electrical engineering is a technical discipline concerned with the study, design, and application of electricity! Through electrical engineering, we can design devices and systems using electrical components such as resistors, capacitors, transistors, etc.

What is electrical voltage?

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).

Which comes first current or voltage?

So, if "current" is only the movement of charge caused by voltagethen voltage has to come first, but if current can be the movement of charge by any means, then current can come first.

What is current, voltage power?

An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge.

Why you want to be an electrician?

Working with electricity is a fulfilling career because it requires an electrician to have a good working knowledge of the relevant electric codes. Electrical work doesn't get tedious, because every day brings something new and fresh to the profession. It also offers tremendous benefits and career potential.

Is battery DC or AC?

Batteries and electronic devices like TVs, computers and DVD players use DC electricity - once an AC current enters a device, it's converted to DC. A typical battery supplies around 1.5 volts of DC.

Is solar DC or AC?

Is Solar Power AC or DC? Solar panels produce direct current: the sun shining on the panels stimulates the flow of electrons, creating current. Because these electrons flow in the same direction, the current is direct. An inverter in a home, converting DC to AC.

Why DC is not used in homes?

Direct current can not be easily stepped up or stepped down with the help of transformers whereas alternating current can easily be converted from low voltage to high voltage or vice-versa with the help of transformers. The possibility of electrolytic corrosion is more in DC than in AC.

What is MCB where it is used?

What is MCB. MCB stands for Miniature Circuit Breaker. It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuit conditions. However, fuse may sense these conditions but it has to be replaced though MCB can be reset.
