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

Since the SAME electrons have to go through both light bulbs, the current in both light bulbs will be the same (Kirchhoff's current law).

How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
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.
How does light bulbs in a circuit affect the current size?
They don't unless you speaking about a parallel circuit in which total currect would be the sum of all the currents in each light bulb (The more light bulbs, the more current draw) If you're talking about a series circuit, nothing at all happens to the current, as in a seires circuit current is constant throughout the entire circuit (voltage changes). In a case such as this the more light bulbs in the circuit, the less the voltage becomes across those bulbs (furthest from the source), thus they will become dimmer due to lower power (P=IE).
How does electric current flow in the b connection?
how does electric current flow in the b connection? do the two bulbs in a series circuit, light when the middle bulb is loose? why?
Does a flashlight use parallel circuit or series circuit?
Well it can depend on how many bulbs it has etc, but generally it would be a series circuit.
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.
This circuit is a series circuit because?
the same current flows through both light bulbs
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
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.
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 does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?

What would be different about the circuit if a resistor were added in series with the light bulbs?
The total current in the circuit will decrease.
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 is an electric current flowing in only one direction?
In a series circuit, then yes, there is only one pathway. For example: if one bulb fuses, all the bulbs in the serial circuit will go out. But there are more pathways in a parallel circuit. For example: if one bulb fuses, all the other bulbs in the parallel circuit will still light.
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.
A W bulb and a W bulb are connected in series in a circuit Which bulb has the greater current flowing in it?
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
