Electric Circuits

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

Ohm's Law states that...

• ...the electricity is a series circuit will always be constant

• ...current is directly proportional to potential difference when temperature is constant

• ...current is directly proportional to power in a wire at constant potential difference

• ...voltage and current increase except in a thermistor
