What would happen if two secondary winding were connected in parallel with the wrong polarity?
Quite simply, they supply electricity in addition to each other and each lead will be connected to the opposite polarity lead of the other winding... you have a short circuit. The transformer will rapidly get hot and if it has no thermal fuse, might start a fire or cause other damage.
What will happen if current transformer polarity reverse in equipment connection?
CHU CHU happens It depends upon the equipment and what you are doing with it. It is easy to remedy the situation but swaping the secondary leads, but the electric drawings must be updated so that people are not confused next time the look at your circuit.
What happens when a curcuit is closed?
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
What ia series circuit?
A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
What is polarity therapy?
A polarity test is used to find out the electrical polarity (positive or negative) of the voltage at a given point within a circuit relative to some other point. Most multimeters, including digital multimeters, can do this.Answer regarding alternating currentIn the context of an a.c. supply, a polarity test is done to ensure that the line and neutral conductors are connected the correct way around at, for example, electrical sockets, Edison-screw lamp holders, etc.
Why should a polarity test be conducted out on a lighting circuit?
to make sure the protection device such as fuse are connected at the live part
What test would identify a short circuit in a lighting circuit?
earth continuity insulation resistance polarity
Why the bulb is not lighting when one wire or terminal is not connected?
When one wire or terminal is not connected to a light bulb, it is not possible for electricity to complete the circuit. When a circuit is not completed, the bulb will not light. An off switch, for example, breaks the circuit.
How do you position the test equipment into the circuits ensuring the correct polarity and without damaging the circuit components?
Lick your own bum
How are the bulbs wires and battery connected?
The equipment is all connected in series with each other to make a complete electrical circuit.
What type of circuit would be used in lighting circuit?
A lighting circuit would be a parallel circuit.
Is Reverse polarity is when the ground and neutral are wired backwards?
If you are talking about an AC (alternating current) circuit, such as the house mains supply, "reverse polarity" usually means the "hot" and "neutral" wires from the supply have been connected to something the opposite way round to what they should be. If you are talking about a DC (direct current) circuit supplied by a battery, such as in a car, "reverse polarity" usually means the positive and negative leads from the battery have been connected to something the opposite way round to what they should be.
Why circuit breaker are connected in series with load?
Because it needs to be able to cut the power to the load. That's why circuit breakers are always the first piece of equipment in a circuit after the power supply.
What would happen if two secondary winding were connected in parallel with the wrong polarity?
Quite simply, they supply electricity in addition to each other and each lead will be connected to the opposite polarity lead of the other winding... you have a short circuit. The transformer will rapidly get hot and if it has no thermal fuse, might start a fire or cause other damage.
What is polarity protection in trunk circuit in telephone?
A bridge rectifier circuit used to convert A.C to D.C. and can also be used as a polarity protection circuit. Because irrespective of which of the input terminals is given +ve voltage , the output voltage is +ve at only one output terminal. hence polarity protected.
Is a dedicated circuit for floor outlets necessary?
It depends on what the amperage of the connected load is. If it above 10 amps on a 15 amp breaker then make is a dedicated circuit. If it is used for lamps in the center of a room, then the floor outlet can be incorporated into the regular lighting and receptacle circuit.
