What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
What happens to current in a series circuit?
the current in series will be same..
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a simple circuit?
The brightness of each bulb in a parallel circuit is the same as the brightness of a bulb in a simple circuit. By Kirchoff's voltage law, each element of a parallel circuit has the same voltage drop across it. With the same voltage, the same type of bulb will dissipate the same power, and have the same brightness.
What happens to the potential difference of a bulb that burns out in series circuit?
The whole circuit fails - because the action of the bulb blowing cuts the circuit.
What happens to the amount of current in a series circuit as the number of batteries increase?
it increases
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
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
What happens to the current in the other lights if one light burns out in a series circuit?
It depends what is the outcome of burning. If that light has created open circuit, circuit will break and there will not be any current. But if there is short circuit means overall resistance is decreased. Thus current will increase. Besides overall brightness will also increase. Thus, if in a series lesser the number of bulbs more will be brightness.
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.
If you unscrewed the second bulb in the parallel circuit when it was on what happens to the first?
Nothing. That's why it's a parallel circuit. If it was a series circuit, then the first bulb would go out.
If you unscrewed the second bulb in the series circuit when it was on explain what happens to the first?
Unscrewing any bulb in a series circuit turns them all off. This is the same as opening the switch that controls them.
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.
Would the brightness of a parallel circuit of 3 globes increase or decrease when a fourth is added?
The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
What happens if there is a break in a series circuit?
The series circuit becomes an open circuit because there is no remaining path.
What happens to current in a series circuit?
the current in series will be same..
