not enough
It is a lab safety supply. It is used to clean the inside of a graduated cylinder after it is used. A graduated cylinder is basically a test tube with markings indicating the volume of the matter in the tube.
Usually Alloy steel is used, copper and brass are also used as boiler tube materials
Any well-stocked hardware store will have clear plastic tube available in several different diameters, usually in or near the plumbing-supply section, and priced per foot.
The best replacement is a new fluorescent light tube of the right voltage and power.
Yes, 1000 ma equates to 1 amp. The 4 amp power supply will have more than enough capacity to operate any device drawing 1 amp.Just make sure that the voltages match. AC voltage of the power supply to AC voltage on the device. You can not cross voltages using a DC power supply to operate an AC device, or the other way around, an AC power supply to operate a DC powered device, even though the voltage values are the same.
No, and neither can the amplified output of a vacuum tube.
ANSWERS; Transparent
The first power supply was created in the 1920s, as devices used for powering residential and commercial radios. Many changes have occurred over the decades from using vacuum tube linear regulators, to the use of semiconductors, and eventually fault tolerant devices.

By Khalid BetaniDirect current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.So the function of a DC Power Supply is to provide Direct current to various accessories of computer such as Hard Disk, Ram, Picture Tube or LCD, Mother Board, CD Rom/DVD Rom, etc, so that they function properly.

Starters in tube light uses capacitors to produce a momentary high voltage of 400V due to discharging of capacitor. This momentary high voltage will start the gaseous discharge to priduce light by initial flickering . now,if capacitor is not used , the power supply from the main cannot start the gaseous discharge .
A large positive charge at the face plate of a CRT; in the order of 14,000 to 31,000 volts, is necessary to attract the electron beam from the neck of the picture tube to the front surface of the tube. There is a separate power supply in most CRT based viewing devices that supply this voltage. Large CRT's usually require higher voltages. High light outputs on any CRT requires more power from the high voltage supply than low light outputs. High voltage is also known as Extremely High Tension, EHT. VE T11.
Each artist finds and performs different settings for their personal machine, allowing the artist to feel comfortable using the machine. The type of skin the client has, along with the size or type of tattoo, determines the setting of the machine and the power supply. Plug in the power supply and attach the cord to the tattoo machine. Place the tube in the tattoo machine and insert the needle in the tube. Tap the foot pedal to ensure the machine is working. Adjust the springs on the tattoo machine to control the depth. Apply pressure with the hand that holds the machine, pressing down into the skin for more depth after adjusting the springs. Turn the voltage of the power supply up to adjust the speed. The more voltage, or higher setting, of the power supply equals a quicker speed. A lower speed is optimal for tattooing bony areas of the body and high speeds for fleshy parts.
