How do you de-energize a circuit?
To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
What is a lump circuit?
A lump circuit is a circuit that concentrates energy in specific frequencies. This is done instead of distributing it over a length of time.
What happens when you connect the line wire from the switch to the load wire from the wall?
This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
What is the term used to designate the point in an electrical circuit where electrical work is done?
the load
When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
Does electric dryer get damaged by short circuit in socket?
The fuse is there to disconnect the supply when there is a short circuit, before any damage is done.
How do you correct a short circuit?
A short circuit is repaired by first finding out where the short circuit occurred. On major faults usually the wires are removed and new wires are installed. On minor faults, the wire that shorted is separated from the offending wire or separated from the grounding medium. To put the conductor back into service the wire's insulation has to be brought back to the level of what the wire was when it was new. Once that is done the circuit can be re-energized.
What are the three main characteristics of circuit training?
Different activities you can do it in any space Can be done at different intensities
What does an fuse do in an circuit?
A fuse protects the (expensive) circuit for too high currents. When the current becomes too high the (cheap) fuse melts and the current is stopped, preferably before damage has been done to the circuit.

How do you change star to delta?
In motor starters, this is usually done using contactors. Explanation of this can easily be done using a circuit diagram. There are three contactors, the main, star and delta contactors-all these contactors can be the same type. There are many ways of wiring a star delta but here I will only give a generalized answer. First, the main contactor and star contactors are energised thus the motor runs in star. After about 5 seconds, the timer which gets energized at the same time as the main and star contactors, switches its CONTACTS i.e the normally open closes and the normally close opens. This dienergize the star contactor and energized the delta contactor. Thus, the motor now runs in delta.
What should be done before disassembly of the electrical system?
remove prime power remove prime power,circuit breakers are off , switches are off
What is a circuit board that controls all work done by the computer?
The small circuit board that controlls the work done by the computer is a DOCUMENT.

What does within three months mean?
"Within three months" means before the end of the three-month period or at any time during the duration of the three months.
Pwm generatoe circuit?
Pulse Width Modulation generator circuit is mainly used in controlling DC motors in connection with the constuction of different kinds of robotics.It basically tests a robots motor funtion, which can be done before the robot is built.
