Exploring Light Bulb Brightness in Circuits

It becomes dimmer.

It burns out.

It remains the same brightness.

It flickers.

Because the power increases.

Because the current decreases.

Because the resistance decreases.

Because the voltage increases.

The total resistance decreases.

The brightness of each light bulb decreases.

The brightness of each light bulb increases.

The voltage across each light bulb increases.

Because the total current decreases.

Because the voltage across each light bulb is the same.

Because the current through each light bulb is different.

Because the resistance of each light bulb changes.

It increases.

It remains the same.

It fluctuates.

It decreases.

By multiplying the resistances.

By adding the resistances.

By dividing the resistances.

By subtracting the resistances.

0.08 amps

0.12 amps

0.06 amps

0.04 amps

By dividing the total voltage by the number of resistors.

By multiplying the current by the resistance of each resistor.

By adding the resistances.

By subtracting the total resistance from the voltage.

4 volts

2 volts

6 volts

8 volts

Because the power is lower.

Because the voltage across each light bulb is higher.

Because the resistance is lower.

Because the current is lower.
