What else can I help you with?
What type of protection scheme is employed for protection of a large form of transformer against shortcircuit with neat sketchs discuss the working principle?
You've got to be kidding! The answer would require a chapter in a textbook, and not a response in this forum.
What are the differences between isolator and circuit breaker?
isolator is a off load device which is used for isolating the downstream circuits from upstream circuits for the reason of any maintanance on downstream circuits. it is manually operated and does not contain any solenoid unlike circuit breaker. it should not be operated while it is having load. first theload on it must be made zero and then it can safely operated. its specification only rated current is given.but circuit breaker is onload automatic device used for breaking the circuit incase of abnormal conditions like shortcircuit, overload etc., it is having three specification 1 is rated current and 2 is short circuit breaking capacity and 3 is instantaneous tripping current.
What is it when too much current flows through a conductor?
Overcurrent, sometimes called shortcircuit.
How to know if being tracked with mobile phone?
No way to really know, if you think you are then you can shortcircuit the chip in your phone.
What could be the cause the power mirrors are not working in Mercedes C280?
Could be the switch between the front seats, or a fuse, or a shortcircuit in the wire with power from the battery.

Why Mercedes C180 engine stops?
The question is really "big". There are hundreds of malfunction that can stop the engine. Coud be the gas pump, the battery, or the lack of pressure in the fuel line, or the step by step device, or the fuel filter or the electronic system or some shortcircuit in the start key.
How short is a shortcircuit?
A short circuit is so short that all the current in the entire network prefers to pass through it! Actually, whenever in a network/circuit there are two parallel paths for the current to flow, the current chooses the path of least impedance. As such, a circuit with no impedance of any sort is called a short circuit cuz the entire current passes through it.
On a Seat Cordoba all bulbs are working yet the headlights wont work why?
More than likely there is a short in your electrical circuit either between the headlights and your switch or in your Headlights fuse. Check under the bonnet near the battery for a fusebox then check for the Headlights or Headlamps fuse then check to see if the fuse has been blown (the fuse will be in a seethrough casing and the circuit will be separated). Another good tool to get for yourself is a simple voltmeter, you should be able to find a voltmeter for about 10 to 30 euros and then read the instructions. When checking for automotive circuits set your voltmeter for DC voltage then place your positive probe on one part of the circuit and your negative probe on another part and note the reading. If the reading fails to read toward normal voltage (12-14VDC) then you have identified the shortcircuit and may be able to replace the shortcircuit or inform your mechanic or dealership or agency of your problem.
Can a 12 volt DC gearmotor run directly off a 12 volt auto battery?
No everyone thinks that but youcan get a shortcircuit it is always good to go above and beyond just incase. Sure you can, that is what the gear motor is rated at. With the engine running there is an output of 13.8 volts coming from the alternator. Just make sure that there is a fuse between the battery and the load for the protection of the battery, if the gear motor ever shorts out the fuse will open the circuit.
1992 Tercel has new battery cables a good battery and no electrical anywhere on the car.door chime cig liter lights etc Battery tests 12.2v What could cause a complete blackout of all electrical?
a bad groundIt has either a (inline)fuseable link or a fuse between the battery and the back of the fuse panel.Check to see if there is a small wire(approx.16/18 gauge) attached to the starter solinoid where the battery cable connects at:If so the fuseable link will be in that wire.It is larger than the wire itself.But beware there had to be a MAJOR shortcircuit to burn this out.If you wire around this, your car can become a torch.
If an adaptor is marked with output 12v dc and 2000mA does this mean the appliance draws 2amps when in use?
Yes and No. You have three types of adaptors: constant current with variable voltage output. constant voltage with variable current output. constant voltage with constant current output. What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use. Heavier appliance will not draw enough current/voltage and will malfunction. Lighter appliance will draw too much current/voltage and will overload/shortcircuit.
What happens when you use a smaller resistor in place of larger one?
as we can deduce from its name, the resistor "resists" to the current (the movement of the electrons) so as the value of the resistor increases, the current flowing through it decreases. so when you use a smaller resistor, the current increases, however the tension between its poles decreases ( due to the voltage divider law). remember that the shortcircuit is due to the small value of the current , so we need always to have a resonable resistance on the circuit..... but not too high because joule losses we'll be more significant !! hope i've been clear :D
