If the circuit has not damaged the bus bars in the distribution panel just change the breaker out for a new one. If the wire insulation has burned you might want to think about changing the wire for a new one. Wire burn back is caused by loose terminal connections at the breaker. As a general maintenance procedure shut off the main breaker and go over all of the breaker terminal connections to make sure that they are tight.

According to what I know, rapping motor is the motor that is connected to rapping system. Rapping system may contain a shaft with a lot of hammers hanging on it. The function of this rapping system is to give impact force that will result in vibration of the parts that are hit.

hey!! let's see how we can figure this out, cool?!


let's label some things first.


Vbattery = 23.7 V


R1 = 22.7 ohms
R2 = 39.3 ohms
R3 = 6.70 ohms


here's a little diagram..

GND-------[- Vbattery +]-----------[ R1 ]-------[ R2 ] -------[ R3 ]-----------GND

current, I, will be flowing through this circuit.
but which way?

current flows out of the + part of the battery.

so real fast, let's add something to the diagram, cool?

I
------------>

GND-------[- Vbattery +]-----------[ R1 ]-------[ R2 ] -------[ R3 ]-----------GND


I
<------------
all the elements are in series, will there be a constant current or constant voltage?!


you're right !! there's a different voltage drop at each resistor, so the current must be the same throughout the entire circuit. i kept drawing the voltage drops, but the picture is busted when saved. =(


k, let's ask that dead guy, mr. ohms, for his equation.. k, cool, it's V = I x R.


(1) solve for I
I = V/R = Vbattery/(R1 + R2 + R3) = 23.7V/68.7ohms = 0.33498 A
= 0.33498 A x 1000
= 334.98 mA
(2) solve for VR3 - voltage (drop) across 6.7 ohm resistor
VR3 = I x R3 = 2.31 V < ur answer.


(3) check
VR1 = I x R1 = 7.83 V
VR2 = I x R2 = 13.56 V


VRtotal = VR1 + VR2 + VR3 = 23.7 = Vbattery !!


yay.

Explain the construction details of DC Machine with neat diagram?

It depends on the source of DC that is powering the inverter. Since the inverter is 2000 watts, that just means it will handle your 1500 watt application. At 120 VAC you are drawing a little over 12 Amps. If this is an inverter plugged into a car it will run until the battery runs down, whose time will be lengthened if you keep the car running. Your battery will have an Ampere per Hour rating. If for example you had a 50 AHr battery it could supply 50 Amps for an Hour so your heater would run for about 4 hours.

Either the load is changing or there is something wrong with the testing method or there is no voltage regulation and the voltage is varying wildly.

In SI, the 'volt' is a special name given to a joule per coulomb.

The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.

Earth leakage current or ground leakage current is current going where it is not supposed to be going (whether it is on a laptop or not). Power line current should only flow between hot and neutral. The earth or ground line is only there for safety purposes to keep the metal chassis at 0V at all times.

For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators).

Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.

This describes what is known as the 'fault level' at a particular point in an electricity transmission or distribution system, expressed in megavolt amperes, enabling the theoretical value of fault current to be calculated at that point in the system, in order to ensure that the relevant switchgear is capable of interrupting that level of fault current.

A retarding voltage is what causes the electronic to shut down.

What is a set up sheet for an event

The magnetic leakage should be very small and designers go to some lengths to reduce it as far as possible because it causes leakage inductance, which is a bad thing. Ideally the magnetic field must be confined to the magnetic core of the transformer.

Amperes are a unit of electrical current flow, in coulombs per second. Volts are a unit of electrical potential difference, in joules per coulomb. The two units can not be converted without some intervening device characteristic such as resistance or power.

The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.

Frequency and voltage, yes. Amperage - desirable but not mandatory. Paralleled generators that are equally sized generally have a load balancing control that accomplishes this function. Generators that are of different ratings may be loaded to different current levels because of their capacity limitations.

PLC logic is a digital computer used to automate electromechanical processes. The Star delta diagram is a diagram for a simple circuit that has the capabilities of starting a high horse power motor. A star delta diagram can be drawn in PLC Logic.

MP2 and MP4 are two different gun types. MP2 guns can only shoot 2 rounds at a time, while MP4 can shoot 4 rounds at a time. MP6 and MP8 are higher round counts for larger and more powerful weapons.

current would go to a maximum, (if there was voltage present), if there was no voltage, no current would flow. the only thing that would limit the current flow (if voltage is present) is the small resistance of the cables, but say there was no resistance it would be like in a short circuit maximum current would flow at the instant voltage is applied. that is why RCD's work as they should, you want the most amount of current to flow at once because otherwise if the current was limited it would not trip in time to stop someone getting electrocuted.
