When two identical 115-volt light bulbs are connected in series to a 240-volt supply, the voltage is divided equally between the two bulbs. Each bulb would receive 120 volts, which is higher than their rated voltage of 115 volts. This excess voltage can cause the bulbs to overheat and potentially burn out quickly, leading to a failure of both bulbs. Thus, it's not recommended to connect them in this manner.

Three identical bulbs are connected in series labeled A B and C to a battery which bulb is the brightest?

If three identical bulbs are connected in parallel to a battery, all three bulbs would have equal brightness.Kirchoff's voltage law states that the signed sum of the voltage drops around a series circuit is zero. A consequence of this is that, in a parallel circuit, the voltage across each parallel element is the same.There are effectively 6 series circuits in this example - battery and A - battery and B - battery and C - A and B - A and C - and B and C. These six combinations are also parallel circuits, and they are also in parallel with each other.


Are lamps in house connected to series or parallel?

They can be connected to either supply. A bulb in series that fails, will cause all the other bulbs to go out. A bulb in parallel that fails, will have no adverse effect on the other bulbs in that circuit


When several light bulbs are connected in a series circuit what will happen if on bulb burns out?

Hmm. well, it's a series circuit, so I would think they would potentially follow after the one that went out, right?? Yeah, for sure!


What is the effect on total resistance of adding this third bulb?

If a fourth bulb were added in a similar way to the three existing bulbs, the resistance in the circuit would go up if the bulbs were series connected, and it would go down if the bulbs were parallel connected.


What will happen to the current if you add more bulbs to the cirrect series?

current will decrease

When two light bulbs are connected in series the?

When two light bulbs are connected in series , there is voltage drop which causes the second lamp to dimAnswerWhen two lamps are connected in series, neither lamp will be subject to its rated voltage and, so, each lamp will be dim. Surprisingly, perhaps, the lamp with the higher power will be dimmer than the lamp with the lower power!


Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?

The bulb that will glow first when 3 bulbs are connected in series and the switch is connected after 1 bulb is the second bulb in the series. The current flows through all the bulbs in a series circuit, but the second bulb experiences the full potential difference first as it is connected directly to the source.


What happens to the brightness of the other two when one of the bulbs burn out three identical bulbs are wired in series?

As a series circuit, as asked, all bulbs will go off because of that just one bulb.


Why are two bulbs in a series dim?

Two bulbs in a series are dim because the resistance in the circuit increases when the bulbs are connected in series, dividing the voltage between them. This results in less power being supplied to each bulb, making them appear dimmer compared to when they are connected in parallel.

Why bulbs connected inparallel?

all the bulbs must in parallel because all must get the same voltage.......in parallel voltage is constant.if they are connected in series they will not get same voltage


What type of circuit is it called when light bulbs one after another are connected?

In series


Is it true that when a round bulb and a long are connected in a parallel circuit the long bulb is brighter than the round bulb?

In a parallel circuit, the brightness of the bulbs connected depends on their resistance and current flow, not their physical shape or size. The bulbs will have the same voltage across them, so if the long bulb has a lower resistance, it could be brighter but this depends on the specific characteristics of the bulbs.


How can you connect bulbs in series?

A Bulb can be connected in a series in such a way that the energy source which is applied want to flow equally across the bulbs connected in series. A Bulb has to knobes or holds in which we supply the power. Assume one knob as a positive voltage absorbing source and other has a negative voltage absorbing source. When we connected in such a way that we can apply the voltage continuously in which the bulb will blow easily. When two or more bulbs are connected in series like end of the knob of one bulb i.e., negative to the next positive of the next bulb in series and negative of second bulb to the positive of the third bulb. Then the voltage splits equally across the bulbs connected.


How are the bulbs wires and battery connected?

The equipment is all connected in series with each other to make a complete electrical circuit.


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.
