Series and Parallel Circuits

These flashcards cover key concepts related to series and parallel circuits, including definitions, laws, and differences between series and parallel configurations.

Series Circuit

A circuit where there is only one path for the current to flow.

Parallel Circuit

A circuit where multiple paths are available for current to flow.

Conventional Current Direction

Flow from positive to negative.

Resistor

An electrical component that resists the flow of current.

Ohm's Law

The relationship V = IR, where V is voltage, I is current, and R is resistance.

Voltage Drop

The reduction in voltage across a component in an electrical circuit.

Kirchhoff's Voltage Law

The sum of the electrical potential differences (voltage) around any closed network is zero.

Current

The flow of electric charge, measured in amperes (amps).

Power (Electrical)

Rate at which electrical energy is transferred, calculated as P = IV, where P is power, I is current, and V is voltage.

Equivalent Resistance in Series

The total resistance equals the sum of the individual resistances: R_total = R1 + R2 + R3.

Equivalent Resistance in Parallel

The total resistance is found using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3.

Power Delivered by Battery

Calculated using the formula P = VI, where P is power, V is voltage, and I is current.

Energy Transfer

The amount of work done in a specific time, related to power; work = power time.

Amps (Amperes)

The unit of measurement for electric current.

Voltage (V)

Electric potential energy per unit charge, measured in volts.

Resistance (R)

Opposition to the flow of electric current, measured in ohms.
