What is the basic of electrical engineering?
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism.
What is current unit Mcq?
The SI unit of electric current is Ampere. One Ampere is defined as: charge passing per minute. 1 coulomb of charge flowing per second.
Who is the inventor of electricity Mcq?
Most people give credit to Benjamin Franklin for discovering electricity.
What is the direction of electric field Mcq?
Explanation: Electric field originates at the positive charge and terminates at the negative charge. The conventional direction of the field is from positive to negative.
What is AC current and 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 called electric Pressure?
The term to describe pressure in electricity terms is ‘voltage’. It’s measured in volts using a voltmeter.
Who found electric?
Who first used electricity?
Benjamin Franklin
Benjamin Franklin is given the credit for discovering electricity. In the year 1752, Benjamin Franklin conducted an experiment using a kite and key on a rainy day. He wanted to demonstrate the relationship between lightning and electricity. He flew the kite tied with a key during the thunderstorm.
What is the symbol for current?
I
The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère’s force law (1820).
