Voltage / Potential Difference (V)

The energy per unit charge that pushes electrons through a circuit

Current (I)

The flow of electric charge per second

Resistance (R)

The opposition to the flow of current in a circuit

Ohm’s Law

A formula that relates voltage (V)

Series Circuit

A circuit where components are connected end to end

Parallel Circuit

A circuit where components are connected across the same two points

Voltage in Series

The total voltage equals the sum of voltages across each component

Current in Series

The current is the same through every component

Resistance in Series

The total resistance equals the sum of individual resistances:

Voltage in Parallel

The voltage is the same across all branches

Current in Parallel

The total current equals the sum of currents through each branch

Resistance in Parallel

The total resistance is calculated using: 1/R_total = 1/R1 + 1/R2 + 1/R3

Energy Conversion in Renewable Energy Sources

The process of changing natural energy forms to electricity
