What would happen if you tried to operate a dc permanent magnet motor from an ac supply?
Apart from a lot of loud humming, the motor would not turn, it would take a lot of current and, if the circuit breaker did not trip to cut the supply of current, it would probably overheat or might even catch on fire.
What will happen to the lamp if current decreases?
brightness will decrease
What would happen if electromagnetic induction was not discovered?
there's no current
Why should a earthing circuit have low resistance?
The purpose of an earthing (protective) conductor in a residential installation is to allow sufficient fault current to flow, in the event of an earth fault, to enable the operation of the circuit's overcurrent protection device (fuse or circuit breaker), so its resistance must be sufficiently low to allow this to happen.
What happen if you reduced the number of devices on each parallel circuit?
The overall current will decrease by subtracting the current used by each device.
What happen when a fuse wire of 100 ampere is used when a circuit at home draws a maximum current of 20 ampere?
The fuse or breaker should be no bigger than specified for the wiring and devices on the circuit. Your nominal current draw may be 20 amps, but a short circuit would cause maximum current to flow which in this case would be 100 amps until the fuse blew.
What will happen if phase is directly connected to ground?
Assuming a circuit breaker is also installed, then you will have a phase-to-ground fault, or a dead short. This will cause the current draw to spike and extreme heat to be created, which will hopefully trip the breaker, which will stop the current flow. If no breaker or fuse is used, then the wires will eventually catch fire from the extreme heat.
When did Phantom Breaker happen?
Phantom Breaker happened in 2011.
When did Nano Breaker happen?
Nano Breaker happened in 2005.
When did Energy Breaker happen?
Energy Breaker happened in 1996.
What would happen if the live and neutral wires were crossed in a 3 pin household plug?
Current in a standard house is AC (alternate) so it doesnt matter if the live and neutral are crossed. Should the earth and live be crossed then the earth leakage would trip
When did Block Breaker Deluxe happen?
Block Breaker Deluxe happened in 2004.
What will happen to electrical devices if overloaded?
An overload condition is demanding more current than can be supplied. This could trip a breaker, blow a fuse or possibly destroy a device that is drawing too much current.
What usually happens at consumer end when the current carrying capacity of transformer is exceeded?
What should happen is that the circuit-breaker should trip to cut off the current before the transformer becomes damaged by overheating.
What happen when 220v dc is applied to a 220v ac single phase transformer?
The current would rise until it blows the fuse or breaker and that would produce an arc as the transformer's inductance tries to maintain the current.
What do you think would happen if you put a 3A fuse in a plug used for kettle?
I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
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.
