Q:

What are some basic concepts of electrical engineering?

A:

Quick Answer

Some of the basics of electrical engineering are current, voltage and resistance. These are three of the essential building blocks of electricity, and it is important to understand electricity at a fundamental level before learning complex terms.

Full Answer

Electrical current, measured in amperes, is the free movement of electrons across a circuit, or continuous electrical path. Voltage, measured in volts, is the potential energy present in the current to move electrons from one specific point to another. Resistance, measured in ohms, is the friction imposed on the electrons as they travel within the circuit.

Current, voltage and resistance are directly proportionate, as displayed by Ohm's law. This equation states that voltage is equal to current multiplied by resistance. If two elements of this equation are known, the third can be solved for.
