Electricity

circuits

series

Voltage is shared

Current is the same everywhere.

If one bulb goes out, so does the other.

parallel

Voltage is the same for all branches

Current is shared.

If one bulb goes out, the other/s will stay on.

current

Measured in amps (amperes)

Is a flow of charged particles.

Conductors let current flow.

Insulators stop current from flowing.

charges

positive

negative

Like (same) charges repel (push away).

Unlike (different) charges attract.

static

Electrons rubbed from one thing to another.

Charges can't move so charge builds up.

Charges move when circuit completed-shocks, sparks.

resistance

Makes if hard for particles to move.

The more resistance the smaller the current.

electromagnets

Wire coil and an iron bar with a current going through.
