How do you make power supply variable?
A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages. Once a circuit is connected to it, the output would not normally be changed.
What will happen when the shunt motor is connected across the supply line directly?
If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!
What is the purpose of a supply line in plumbing?
supply potable water
Would the amount of light increase decrease or remain the same when lamp is placed across a 120 V dc power line?
When a lamp is connected to a power supply the total amount of light increases.
Why can a reactive power load drop the voltage more than the active power load in a transmission line?
A load with a poor power factor draws extra current from the power supply, meaning that there will be more of a voltage-drop in the supply. As an example, if the load is 6 kW on a 240 v supply, the current drawn is 25 amps if the load has a power factor of 1. The kVA is equal to the kW. But if the load has a power factor of 0.8 it needs to draw 7.5 kVA for a power of 6 kW, which is a current of 31.25 amps, so there is more of a demand on the power supply wiring etc. The transmission losses increase by 56% with the extra current. In both cases the customer is charged for power used, 6 kW. That is why the supply companies do not like loads with a poor power factor and sometimes charge commercial customers more for a poor power factor. That in turn makes it viable for the customers to correct the power factor of the load they place on the supply.
What is the function of the power supply cable?
· A power cord, line cord or mains cable is known as the supply cable, which temporarily connects an appliance to the mains electricity supply to a wall socket. · A supply cable connects the refrigerator to the mains electricity supply via a wall socket.

How do you eliminate engine whine in a CB radio?
The whine probably comes from the alternator. You will need a supressor on the alternator output. Another way, is to use an in line filter in the power supply, to the CB, to stop interference on the power supply from reaching the radio. You need an auto shop to check the alternator. The in line filters can be got from radio Shack and look like an in line fuse.
Where are fuel filters on a lawn mower?
There will be an inline filter on the fuel supply line from the tank to the carburetor
What is line in line regulation?
Line refers to the a.c. supply line. Line regulation is the change in output of a device, usually a power supply, which is due to variations in the voltage of the a.c. supply.
How the Operation of direct online Starter?
A direct line starter is a simple motor starter used to power electric machines. It works by coupling the motor to the power supply directly at full function.
What is a function of a power supply in a computer?
It converts "line voltage" (where you plug the computer in) to various DC voltages that have been filtered and made more usable for the processor and other components.
What is a function of neutral wire?
to complete the circuit and back to power supply
When you log transform a power function the resulting function is a straight line?
Yes, the resulting function is a straight line. This is the source:http://www.mathbench.umd.edu/mod207_scaling/page10.htm
What distinguishes a linear function from other functions?
A linear function is one in which the power of the function is only one. So, the graph of it would be a straight line. For example, x2 + x = y is not linear, because the highest power is 2. A main difference is, non linear functions have curves, where as a linear function is a straight line, with the exception of when the function has a power of 0, and it is technically a straight line.
Can CAT5 wire be used to supply power?
Yes. A Cat-5 line can be used to supply power to certain Ethernet Switches that support POE, or Power Over Ethernet.
What are zeros of the Function?
The zeros, or roots, of a linear function is the point at which the line touches the x-axis. Since a linear function is a straight line, it has a maximum of one root (zero). The zero of a function can be determined by the highest degree (power) of the function. Since linear functions are only raised to the power of one, one is the total number of times the line can touch the x-axis. If you function is a horizontal line, it has no root, or zero.
