A: ANY CABLE will have a definite impedance and if current flow there is going to be a definite voltage drop because of it
It should decrease
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.
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.
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.
•A cable runs continuously in a channel between the tracks, which are located just below the street. The cable is controlled at a central station, and usually moves about 9 miles (14-5 kilometers) per hour. On the underside of each cable car is an attachment called a "grip." When the car operator pulls a lever, the grip latches onto the moving cable and is pulled along. When the operator releases the lever, the grip disconnects from the cable. The car comes to a halt when the operator applies the brakes. Also called an endless ropeway
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
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.
A voltage drop of 0.4 volts in a 12-volt system represents a drop of about 3.3%, which is generally considered acceptable for many applications. However, the acceptability can vary based on the specific requirements of the devices being powered and the length of the wiring. For critical applications or longer wire runs, aiming for a lower voltage drop is advisable to ensure optimal performance and efficiency.
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.

The cable that runs from the throttle body to the transmission is the detent cable. The other cable is the speedometer cable.
Because in the real world, all cells have some internal resistance and when a current runs through that resistance, there is a voltage drop.
Firstly, check how long this circuit is (in metres) as loss of voltage increases as the length of the cable run does and so you may need to 'upsize' the cable's cross-sectional area to allow more current and reduce the loss. If it is just one breaker then you likely have a bad breaker that needs to be replaced. Another possibility is that your ground is floating at about 40 volts. This would typically cause problem for all breakers (circuits). Check connection to ground rod and bonding in panel between neutral and ground at main panel only. If you can provide the precise circumstances when this happens, it can help with diagnostics.

The ampacity of 12 gauge wire is typically around 20 amps. However, for a 300ft length, voltage drop becomes a concern. It would be advisable to consult the National Electrical Code or a qualified electrician to determine the appropriate wire size for the application.
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.
