Basics of Electrical Engineering and Circuitry

These flashcards cover key concepts and terminology related to electrical engineering basics, specifically focusing on voltage, resistance, current, and circuit types.

Voltage

The electric potential difference measured in volts, represented by the letter V.

Resistance

The opposition to the flow of electric current, measured in ohms, represented by the letter R.

Current

The flow of electric charge measured in amperes, represented by the letter I.

Parallel Circuit

A network of electrical components connected to the power source by separate paths, maintaining consistent voltage across all components.

Series Circuit

A circuit where components are connected end-to-end, so there is only one path for current to flow.

Total Voltage (VT)

The total electric potential in a circuit, which remains constant in parallel circuits.

Total Resistance (RT)

The overall resistance of the circuit, calculated using the formula: 1/RT = 1/R1 + 1/R2 + 1/R3 for parallel circuits.

Ohm's Law

A fundamental principle relating voltage (V), current (I), and resistance (R), typically expressed as V = IR.

Amperage

The measure of electric current, which can vary within different branches of a parallel circuit.

Common Denominator

The smallest number that two or more denominators can all divide into, used when adding fractions.
