What happens when you add a resistor to a series circuit with a light bulb?

As you add more bulbs to a series circuit that means that the bulbs are in series to one another, therefore the total resistance is the sum of the individual resistance of the bulbs. If you add bulbs of the same resistance,then the rate at which the resistance changes will increase in a constant manner provided the current source is not altered. For instance if the bulb you are using is rated 20v,60w, then the current passing via the bulbs in series is the square of the voltage divided by the power in this case the current is approximately 7amperes.

∙ 12y agoWhen a resistor is added to a series circuit, the voltage across each of the original
elements in the circuit decreases, the current in the circuit decreases, and the total
power dissipated by the circuit also decreases.

If there is a resistor in the circuit, it will cause some of the energy that would normally be converted to light to be converted into heat instead, so the light bulb will glow less brightly.
A variable resistor in such a circuit is sometimes called a "dimmer".

What happens if you take a device out of a series circuit?
the light bulb gives off more light
What happens when one light bulb burns out in a series circuit?
All of the light bulbs in the series circuit would go out.
What happens to lights in parallel if one goes out?
In a series circuit each light completes its part of the circuit and connects to the next light. So, if one light fails, the circuit is broken and the flow of current to all lights must stop.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
What products use Variable resistor?
Toasters and lightbulbs.AnswerA resistor is an circuit component. So, while toasters and light bulbs have resistance, they are not resistors!
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.
What happens in a series circuit if a light blows?
The circuit current is interrupted and all the lights will go out.
What happens when a light bulb is broken in a series circuit?
In that case, the entire circuit won't work.
What if you were to add a resistor to a series circuit that include a light bulb?
A resistor slows the flow of electricity, and converts the electrical energy into heat. You don't WANT heat - you want LIGHT, so we generally do not put resistors in lighting circuits. If there is a resistor in the circuit, it will cause some of the energy that would normally be converted to light to be converted into heat instead, so the light bulb will glow less brightly. A variable resistor in such a circuit is sometimes called a "dimmer".
What happens if you take a device out of a series circuit?
the light bulb gives off more light
What happens if you unscrew a light bulb in a series circuit?
The circuit will have the flow of electricity interrupted.
What is a seris and a parrel circut?
in a series circuit current flows through each resistor or light bulb and if one item burns out the complete circuit goes dead such were the old fashioned xmas tree lights. They were wire in series and if one light burned out you had to test each light bulb til you found the one burned out to get the whole string to work again. In a parallel circuit each resistor, motor, light bulb has its own ground so if you lost one light in a circuit the rest of them continue to burn.
What happens if one bulb in a series circuit burned out?
In a series circuit, all bulbs are necessary to complete the circuit. If one bulb goes out, the circuit is broken, so none of the bulbs would light up.
What happens when one light bulb burns out in a series circuit?
All of the light bulbs in the series circuit would go out.
What happens to a series circuit if a longer wire is used?
Resistance is increased so the light will be dimmer.
What happens when you unscrew a light bulb in a series circuit?
If you unscrewed any bulb in the circuit it would turn all of the bulbs off.
What happens to the voltage across the voltage source as more light bulbs are added in a series circuit?
Nothing.
