What happens when a light bulb is unscrewed in a series circuit?
All other light bulbs will turn off due to the series circuit being broken. The electrons cannot travel all the way through, hence the current will also not flow in the circuit, switching off all the other bulbs too.CommentIt's worth pointing out that the full supply voltage will then appear across the lamp holder -so take care!
What happens when one light bulb goes out in a series?
The failed bulb breaks the circuit so no current can flow - so the other bulb goes out (but is OK).
A string of 15 chrimas tree lights is connected in series to a 90 volt power source what is the value of the resistance of each light if the current flowing through the circuit is 2 amps?

Based on what you have seen what must be true for a circuit to light a bulb?
There must be a current through the bulb in order for it to glow.
What can you do to a closed circuit consisting of a battery a light bulb and a switch that would decrease the amount of current?
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.
What do amps do in a series circuit?
In a series circuit, the current (amps) is constant throughout the circuit. This means that the same amount of current flows through each component connected in series. The current is not divided or reduced as it travels through the circuit.
This circuit is a series circuit because?
the same current flows through both light bulbs
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
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 when you unscrew a light bulb in a series circuit?
When you unscrew a light bulb in a series circuit, the circuit will break and all the other light bulbs in the circuit will turn off. This is because in a series circuit, the current flows through each component in succession, so removing one component interrupts the flow of current to the rest of the circuit.
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
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.
The circuit is a series circuit because?
The same current flows through both light bulbs.If one of the resistors run out of power,the whole circuit shuts down
What is a seiries circuit?
Series CircuitWe say Resistances are in series if the same current flows through all Resistances. A circuit containing of only series resistances is called a series circuit. A series circuit is a circuit that has the same intensity of current flow through its elements.
An example series circuit might be what?
A voltage or current source in series with a circuit breaker or fuse in series with a switch in series with a light bulb.
What happens when you open a switch in a series crcuit?
A closed series circuit is one where the current flows through all devices in the circuit. Opening a switch prevents current from flowing in the circuit and it becomes simply an "open circuit". Any device that operates with current (light, LED, motor, etc) will no longer function.
If a wire on a series circuit is disconnected what will happen to the two lights?
If a wire on a series circuit is disconnected, both lights will go out. In a series circuit, current flows through each component in sequence, so if the circuit is broken by disconnecting a wire, the current cannot flow through either light.
