The voltage across a purely inductive load leads the current by 90 degrees.
Because of this 90 degree offset the power transfer is inefficient because the current and voltage peaks are never aligned.
P = I * E
Therefore a capacitor with an reactance equivalent in magnitude but opposite in polarity to that of the inductive load at the operating frequency can be placed in parallel with the load to maximize power transfer.
CommentPower-factor improvement does not improve, or increase the efficiency of, power transfer. The power of a load is exactly the same after power-factor improvement as it was before power-factor improvement. All that power-factor improvement does is to reduce the amount of load current.

If you charge four 50v capacitors in parallel then remove the 50v battery and hook it up to a volt meter will the meter say 50v or 200v?
If you charge four 50v capacitors in parallel then remove the 50v battery and hook them up to a volt meter the meter will indicate 50v.
Do you hook up the ground wire first to an amp?
No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..
What is the machine called that you hook up to a tractor power take off to test for horse power?
Dynamometer
How do you hook up two amps at a time?
Not that hard you will need a power distribution block this splits your main power wire. One in and 2 out just hook up each amp power to any of the 2 empty spots on the distribution block.
Do you hook up white or black first when changing a light fixture?
As the power to the light fixture should be, and hopefully is off, it does not matter which you hook up first.
Do you need to hook up a power cable if your using SATA drive?
Yes; power is not supplied by the data cable. An exception might be a small-form-factor, external, USB-connected drive, as the USB port can power low-power devices. If an external USB hub is expected to power external devices, it's best if the hub itself is powered, otherwise available power is split among too many devices, potentially leaving something underpowered.
No power to trailer hook up running lights where does the factory wiring harness hook up under the dash?
it is under the hood on the driver side in the fuse box
Can a car amplifier be wired in a house to power subs?
yes but u would have to hook the amp up to a power source and ground it
How do you hook up a 3 farad capacitor to two amps?
**** caution**** very much danger......on the cap there should be 2 terminals....+ and a - .....first thing is to undo the power supply the cap goins inline on the (+) side of the power supply and also hook the (-) to the ground inlined with the amp......do NOT EVER EVER EVER TOUCH OR ARC ACROSS THE CAPS TERMINALS....THIS CAN BURN UP THE CARS ELECTICAL SYSTEM AND OR KILL YOU BY STOPPING YOUR HEART.......SO HOOK THE CAP IN BEFORE YOU HOOK UP THE (+) POWER TO THE SYSTEM
Can you hook up subs to factory jeep stereo?
Yu can hook subs up any where but to a stock the power output wont be much so they wont really hit
Can you get electrical power to a vacant lot?
Yes if you pay for the service and pay the hook up fee
How come you get no power in your 1989 winnebago chieftainwhen you hook up the shoreline?
Check the circuit breakers.
