Principles of Engineering

 

Electrical Systems

Electrical - Of, relating to, or operated by electricity.

Electronics - The use of electronics to control a system or machine.

Electrode - A conducting element that emits or collects electrons or ions or controls their movement.

Ohm's Law - The relationship of voltage, current and resistance in a circuit I=V/R, V=IR, R=V/I

Ohm's Law

Current - The total amount of electrons flowing through a circuit per unit time; measured in Amperes

Resistance - The ratio of the potential difference across an electrical component to the current passing through it. It is thus a measure of the component's opposition to the flow of electric charge.

Voltage - The electromotive force in a circuit.

Watt's Law - The mathematical relationship expressing that power is the product of Voltage and Current

Electromagnet - A core of magnetic material surrounded by a coil of wire through which an electric current is passed to magnetize the core.

Electromagnetic Energy - The energy associated with electricity, magnetism, and electromagnetic waves.

Semiconductor - Materials whose electrical conductivity can be precisely altered by appropriate manufacturing processes.

Basic Circuits:

Series Circuit - A circuit with only one pathway for electrons.

 Series Circuit

Parallel Circuit - Multiple pathways in a circuit.

  Parallel Circuit

Series - Parallel Circuit
