series and parallel circuits

Light is part of the electrical spectrum.

Light can be dispersed into the spectrum of colours, each with different wavelengths.

Light is made of only two primary colours: red and blue.

Light is not related to the electromagnetic spectrum.

Voltmeter, in parallel

Ammeter, in series

Ammeter, in parallel

Voltmeter, in series

Series circuit, because current is higher

Parallel circuit, because voltage is higher across each bulb

Series circuit, because voltage is higher across each bulb

Parallel circuit, because current is lower

Current is the same at all points in a series circuit.

Current is shared between components in a parallel circuit.

Current is always higher in a parallel circuit than in a series circuit.

Current is zero in a series circuit.

Current increases

Current decreases

Current stays the same

Current is shared between branches

All components are connected end-to-end in a single path for current to flow.

Each component has its own separate path for current to flow.

Voltage is the same across all components.

Current splits at each component.
