When a battery runs out does the battery voltage increase decrease or stay the same?
It should decrease
How much electric voltage does a VCR use?
All of it! A VCR runs on normal home voltage (120 volts). The voltage drop through the VCR is equivalent to the home voltage. If you're requesting how much power the VCR uses, this is depended on the the VCR - make, model; and whatever the VCR is doing (playing? rewinding? sitting idle? paused? etc.). The best way to find out is to buy a simple power meter. these are available for about 20 bucks. ANSWER: SCR does not run or use home voltage. The SCR can control the load power that is where the usage is. To run a fan at different speed to dim the lights and so fourth. It is a 4 layer diode the current passing trough to the load is the only consideration of the device requirements.
What is cable size for 3 110kw 3 phase induction motor 100 meter run for cable 400v?
first calculate the full load amps of the motor by using formula, line amps = KW * 1000 / (line volts*1.732*P.F) Of the mentioned motor the amps will be 96 amps at the P.F 0.8. The motor will have star delta starter so the cable size would be 2 runs of 3c x 70 sq mm AL if laid in air.
What hp has for motor?
The HP of a motor is determined by the manufacturer of the motor. The after market user or engineer then determines what size of HP is needed to operate their type of designed equipment. When the customer buys the equipment needed for their type of manufacturing an electrician is hired to connect the equipment to the electrical system. The electrician then determine the overload protection, wire size and voltage drop on long conductor runs.
Why does voltage increase with current with separate excitation?
More current in the field coils means a stronger magnetic field for the armature to rotate in. This causes the output voltage for a generator to increase. For a motor, more magnetic field means that the supply voltage can be matched at a slower armature rotation speed, so the motor runs more slowly but can supply more torque.
If you m sizing a cable for 800 Amps and you get a result of 7 runs of single core cable what does it means it is per phase or for 3 phase?
Question is not clear..what size of cable you get 7 runs and Are you using a software or manual calculations. for 800A you need approx. 3cables of 240mm2 for each phase. That will depend also on distance of load and allowed Voltage drop. JH
Operation of on load tap changer in transformers?
OLTC - INSTALLED IN THE PRIMARY SIDE OF A POWER TRANSFORMER TO SELECT OR ADJUST VOLTAGE. THE ADVANTAGE OF THIS IS FOR SOLVING THE VOLTAGE DROP ISSUES IN THE SECONDARY OUTPUT IN THE FARTHEST LOCATION. FOR EXAMPLE YOUR SECONDARY VOLTAGE REQUIREMENT IS 380 VOLTS AND YOU CAN ADJUST TO 400 VOLTS FOR LONG CABLE RUNS.
How do you replace kick down cable on 1972 c20 turbo 350?
You have to drop the trans pan to do it. Remove the cable from the carb and bracket. There is one bolt where the cable runs into the trans. Remove that bolt. After dropping the pan you'll see how the cable is mounted inside the trans. Remove the retaining clip and pull the cable out. Reverse for installation.
What runs by water power and was highly utilized in the South?
cotton gin
What is the cable that runs from from the carburetor to the transmission?
kick down cable
What is the cable going to the transmission on an 88 Chevy k1500?
The cable that runs from the throttle body to the transmission is the detent cable. The other cable is the speedometer cable.
Why observed cell voltages are usually less than calculated E values?
Because in the real world, all cells have some internal resistance and when a current runs through that resistance, there is a voltage drop.
What is the ampacity of 12 gauge wire 300ft long?
20amps but Voltage at end of cable will drop. Not a problem for incandescent lights but might be a problem for motors and electronics. Generally increase wire size to next larger size for long runs, I.e. go to 10# wire. This does not factor in heating in wire under heavy load, but that is generally not a factor unless tightly enclosed.
What size wire do you need for 50 amp sub panel about 200 feet away?
A 1/0 MCM copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 250 feet on a 240/120 volt system. This calculation is for a full 100 amps at the panel. If exact amperage is known the conductor size can be reduced to match the known amperage.
Maximum cable runs for ethernet networks using utp cable is approximately?
330ft
Will a 12v 1.5 amp device work with 12v 2.5 amp replacement power supply?
No. The amperage describes the total electrical energyeither produced or consumed. Voltage just describes the potential. If the power cable or power supply are only capable of 1 amp and the device consumes 2 amps... sorry, you don't have enough electrical energy available.
Which voltage is carried by internet?
The internet does not carry a voltage. Indeed some of it runs over optical infrastructure.
