The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?

ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.


How is the current affected by the number of bulbs?

As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.


In a series circuit what would happen if one of the bulbs stopped working?

All the bulbs will go out. In a series circuit, the current at all points is the same. This is Kirchoff's Current Law. If you loosen or remove a bulb in a series circuit, the current at that bulb becomes zero, and by Kirchoff's Current Law, the current in every part of the circuit also becomes zero.


What happens to the current in a circuit when one bulb is replaced by two bulbs in series?

current in series always stays the same


Compare the current in a 2 light bulbs wired in a series circuit?

In a series circuit, the current passing through each component, like the light bulbs, is the same. This means that both light bulbs would have the same current flowing through them. If one light bulb were to burn out, current flow through both bulbs would stop.


Does the same current pass through each bulb?

If the bulbs are connected in series, the same current passes through each bulb. However, if the bulbs are connected in parallel, the current will split between the bulbs with the lower resistance receiving more current.


In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?

By adding more light bulbs


What would happen to a series circuit if another bulb was added?

A: Adding any resistance bulbs or whatever in a series circuit will reduce current and will reduce total power. In this case the bulb will glow dimmer as any additional bulbs are placed in the series circuit. this is true if the same input source is kept constant.


In a series circuit when adding light bulbs does the current change?

Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.


Which circuit has brighter bulb side by side?

Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.


This circuit is a series circuit because?

the same current flows through both light bulbs


What would happen to the bulbs if three more were added to this series circuit?

Nothing would "happen" to them, but they would glow less brightly.
