How do you know when electric current is flowing in a light bulb circuit?
You know if current is flowing in a bulb circuit because, if there is enough power (voltage times current), the bulb will illuminate. If there is current, but not enough power to illuminate the bulb, you will need to measure the current with an ammeter to see if there is any current.
When is a circuit considered a dry circuit?
when contacts on a switch or relay does not melt enough surface to allow current flow
Explain flywheel effect of a tank circuit?
Fly wheeling or ringing is a process where by circulating current will cause a ringing effect where that is useful is on SCR circuit to reverse power for a shot time enough to reduce holding current therefore shutting the device off
What is the voltage drop for a240 volt single phase circuit 320 feet long. what is cable size required?
Not enough information. To answer this question the amount of current in AMPS the circuit is drawing is needed.
Why electricity does not flow through an open circuit but flows through a closed circuit?
Electricity does not flow in open circuit because the path is not a complete circuit and has the maximum impedance to flow of electricity while it flows in short circuit because electricity always wants a path with least impedance to flow which short circuit is one of such pathAnswerCurrent can jndeed flow through an open circuit. A capacitor is an open circuit, yet it will allow a d.c. current to flow for a short period of time, and an a.c. current can flow continuously.

Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
How do you use a thyristor on a ac circuit?
A thyristor will conduct only if enough gate current is present on the gate and enough holding current flow trough it. Once on it will remain on until the holding current is reached then it will not conduct. Since AC is changing polarity it is possible to apply gate current at any time to make it conduct it will turn off when the AC cannot supply the holding current making it an ideal phase controller
What happens when you tie a knot in a lead of a circuit?
Unless you pull it tight enough to damage the insulation - nothing.
How is an open circuit different from a short circuit?
I guess you could call them 'reciprocals' in a sense.-- "Open circuit". . . Has a very high resistance. Nominally infinite.. . . No voltage, no matter how high, is high enough to produce any current through the circuit.. . . Current through it is always zero.. . . Household example: a light switch that's open (labeled OFF in that position).-- "Short Circuit". . . Has a very low resistance. Nominally zero.. . . Any voltage, no matter how small, is enough to produce very high current through the circuit.. . . Household example: toddler stuck a paper-clip into the two holes of the outlet.
How do you calculate short circuit current?
A short circuit = 0 ohm, from this one can use ohms law to calculate the current, that is E/R voltage divided by resistance as in this instance your resistance is zero and you can't divide by zero so your current will be infinit. In other words if your power supply is large enough to supply 200 amp, your current on a short circuit will be 200 amp.
Can a series circuit work if the bulbs are differently lighted up?
The meaning of "differently lighted up" is very unclear. As long as all the bulbs in a series circuit are connected to the circuit, and all of the bulbs have good filaments with no holes in them, current will flow in the circuit. Depending on the ratings of each bulb, the current may not be enough to cause all of them to glow visibly, but there will certainly be a current. That may or may not suit your definition of "work".
Can people die in an electric circuit?
Yes, quite easily. A current of **** (value blanked for safety reasons) is enough to cause the heart to fail, if a person is unlucky enough to have this happen to them.

Why does my refrigerator keep tripping the breaker?
The most likely possibility is the refrigerator has a problem and needs to be fixed. Another possibility is the refrigerator is on a circuit that does not have enough current capacity to operate it and other appliances that are on the same circuit.
