How does a three bulb circuit compare with the current when two bulbs are bypassed by a short circuit?
The current of one bulb (two bulbs shorted) would be about1 three times the current of three bulbs.
1 I say "about" because resistance is a function of temperature, and running three times the current through one bulb will make that one bulb much hotter, increasing its resistance. It might also burn out the bulb.
What else can I help you with?
In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?
By adding more light bulbs
If you remove one of two bulbs connected to a circuit in a series will the other bulb still shine?
if you have 2 bulbs and one burns out, the other wont shine, if you remove 1 bulb, you are breaking the circuit, and the current cant flow to the second bulb, so no it wouldn't shine.
If you have two 5 watt bulbs connected in series and then in parallel which circuit arrangement will give you brighter bulbs explain your answer?
Brighter in parallel. In series the voltage is divided between the two bulbs, thus the current will only be half so that the power of each bulb will only be one quarter (of 5 watts) in the series set-up.
When one bulb is unscrewed in a series circuit does the other bulb stay lit?
You break the circuit and they both extinguish (go out).Answer: The circuit will open up causing the current to quit flowing to both bulbs therefore there will be no lighted bulbsCommentYou also have the full supply voltage appearing across the empty lampholder!
What is the difference between a parallel circuit and a series circuit?
A parallel circuit is one in which there is more than one current path. An example might be several light bulbs in a house, all of which provide a path for electric current. The advantage is that any of the lamps can be turned on or off without affecting the current flow through any other lamp. A series circuit is one in which the current has only a single path through multiple components. An example might be two resistors, one after the other. Both will have the same current through them but they may have varying voltages depending on their resistance. Another example of a series circuit is a houehold lamp and a light switch. When the light switch is open, no current flows through it and therefore, no current can flow through the lamp either. When the switch is closed, current will now flow through the switch and the lamp.
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.
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.
What happens to the current in a parallel circuit when more bulbs are added?
When more bulbs are added to a parallel circuit, the total current in the circuit increases because each bulb provides an additional path for current to flow. This is because in a parallel circuit, the current is divided amongst the branches, so adding more branches (bulbs) will increase the total current.
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.
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.
This circuit is a series circuit because?
the same current flows through both light bulbs
What happens to the current measured as more bulbs added?
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
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.
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).
What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?
The total current provided by the battery increases as more bulbs are added to a parallel circuit. This is because each branch in a parallel circuit receives the full voltage of the battery, leading to more current flowing through each branch as more loads (bulbs) are added.
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.
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.
