series

The bulbs have the same brightness because the same amount of electric current passes through each load. 

• series circuit

• parallel circuit

The brightness of the bulbs is the same since there is equal electric current passing through each bulb.

• series circuit

• parallel circuit

electric current flows through all the electric devices in one path.

the electric current flows through more than one direction.

Each bulb in the circuit uses only the amount of current it needs enough to light up to its full brightness.

• parallel

• series

Since electric current flows through a single path, when one bulb gets busted or removed, all the other bulbs in the circuit will not light anymore.

• series circuit

• parallel circuit

When one bulb is busted, the flow of current is interrupted, causing the other bulbs not to light up also.

• series circuit

• paralle circuit

travels from the negative end of the battery, then continues through the bulbs and back to the positive end of the battery.

each bulb is connected to the battery separately. Therefore, each bulb is a part of a different circuit.

 is often used in making ceiling lamp decors.
