What else can I help you with?
What will happen to the charges in a circuit a when a switch is closed?
the electrons are not allowed to enter into the circuit.
What will happen to a buzzer connected to an open circuit?
If a buzzer is connected to an open circuit, it will not receive any electrical current and will not produce any sound because the circuit is incomplete. In an open circuit, there is a break in the path, so the electric current cannot flow to power the buzzer.
What does a GFCI protect you from?
A Ground Fault Circuit Interrupter (GFCI) protects you from electric shock by quickly shutting off power to the circuit when it detects a ground fault or abnormal current flow. This can happen when there is a short circuit, a malfunctioning appliance, or contact with water.
Why fuse wire is placed in series with the device?
circuit breaker and fuses used in series to break the circuit in overcurrent situation to block current to flow through 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.
What happen when there is a break in the path circuit?
Current through that part of the circuit will stop.
What happen to the voltage when the collector current increases in a biased circuit?
it dies
What will happen if part of the circuit is not properly connected?
Current stops flowing.
When you add a resistor to a series circuit what will happen to the total current?
increase.
What happen to voltage and current when rheostat is adjusted from maximum to minimum resistance using both ammeter and voltmeter?
When a rheostat is adjusted from maximum to minimum resistance, the overall resistance in the circuit decreases. As a result, the current flowing through the circuit increases, which can be observed on the ammeter as a higher reading. Conversely, the voltage across the rheostat will decrease, as the voltage drop across a lower resistance is less, which can be monitored using the voltmeter.
What happen to current in a circuit if the voltage in not charged but the resistant is double?
In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.
If breaker CT ratio 8001 when current of any phase crossed 800 ampere what would happen?

What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
What will happen to the circuit if the bulb if removed from its holder?
If the bulb is removed from its holder, the circuit will be open, breaking the flow of electricity. This will result in the current being unable to pass through the circuit and the bulb will not light up as a result.
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
Will maximum current flow through 0 ohms of resistance?
In theory, you would get infinite current. But, of course, in practise, this cannot happen, as any large current would cause severe damage to the source supplying that current, not to mention the conductors involved. Protection against such currents would be provided by a fuse or circuit breaker.
What happen to the current in a circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
