BASIC ELECTRICAL CONCEPTS| RRB JE| ELECTRICAL INFO

Here’s a list of basic electrical concepts that can be useful as an introduction to electrical engineering:
Electric Charge (Q)
Fundamental property of matter responsible for electric phenomena.
Two types: Positive and Negative.
Measured in coulombs (C).
Electric Current (I)
Flow of electric charge through a conductor.
Measured in amperes (A).
Symbol: I.
Voltage (V)
The potential difference between two points in an electrical circuit.
Measured in volts (V).
