An AC water heater can be converted to operate on DC current but the cost will be large. In the electrical trade anything can be done if enough money is spent to get the results that are requested.

TFT stands for thin-film transistor. This is the technology for the ultimate LCD display. LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the displays of choice. Nearly all LCD monitors today, including mobile phones, use TFT technology.

An electronic oscillator is an electronic circuit that produces a repetitive electronic signal, often a sine wave or a square wave.

A CMOS gate is a logical switch used in electronics. CMOS stands for Complimentary Metal Oxide Silicon. These types of semiconductors have a very high input impedance, are very sensitive use low current and work over a larger range of voltage.

The alternative is TTL(Transistor to Transistor Logic) which work at 5volts only and draw higher currents.

A gate, is a switch that changes state (on/off) depending on the logic voltage levels applied to it's inputs.

Let's start with understanding viscosity. Your owner's manual may tell you to use SAE 5W-30 engine oil. What does this mean? SAE stands for the Society of Automotive Engineers. They have created a standard for identifying the viscosity characteristics of engine oil. The 5W-30 part of the symbol is actually just a name. The W part of the name is an indicator of low temperature viscosity properties while the 30 part of the name is an indicator of the high temperature or operating viscosity properties. The numbers are just relative indicators to help the consumer. In other words, a 5W oil does not have a viscosity of 5, nor does a 30 weight oil have a viscosity of 30. What the numbers do mean is that the viscosity characteristics of a 5W oil are lower than that of a 10W oil. As well, a 30 weight oil has lower viscosity properties than a 40 weight oil. Its all very confusing, isn't it? The best thing to do is use the appropriate viscosity for your engine and climate as recommended by the manufacturer. In general, newer vehicles will specify lower viscosity oils such as 5W-30 while older vehicles will specify higher viscosity oils such as 20W-50. This is because today's engines are built with tighter bearing clearances to take advantage of the fuel economy benefits of lower viscosity oils. It is not really a good idea to use thicker oil in one of these engines because it will disrupt the oil flow characteristics of the engine and may create excessively high oil pressure. In an older engine that was designed with larger bearing clearances, it is appropriate and recommended to use a thicker oil to maintain proper oil pressure and provide adequate bearing film thickness. This is also true for engines that have a lot of miles on them and the oil pressure is starting to drop off. By using higher viscosity oil, you can boost the oil pressure back to normal levels and increase bearing film strength.

It is a type of electronic test instrument that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis).

Multiplexing is where you represent more than one bit (byte, word, etc.) on one wire (bus, etc.) in different units of time.

In the Intel 8085, the low order address bus and the data bus are multiplexed, each with 8 bits shared on one 8 but bus. There are four strobes involved...

ALE, Address Latch Enable, means that the bus represents address information, specifically the low order address. External hardware is expected to strobe the bus on the falling edge of ALE. Actual address validity occurs somewhat before, around the one third point of ALE, depending on clock speed, so normally ALE is a passthrough strobe, giving external hardware a bit of extra time to decode the address.

WR-, Write Strobe, means that the bus represents data information to write to IO or memory. External hardware is expected to strobe the data on the rising edge of WR-. WR- is low for one and a half clock cycles, not counting wait cycles. The data bus is held valid for one half additional clock cycle in order to assure data setup and hold times.

RD-, Read Strobe, means that the bus represents data information to read from IO or memory. External hardware is expected to drive the data during RD- low, with the processor strobing the data one half clock cycle prior to RD- going high. RD- is held true (low) for one and a half clock cycles, not counting wait cycles. Note very carefully that the timing from ALE to data strobe point is not the same for write cycles versus read cycles. This is by design.

INTA-, Interrupt Acknowledge, means that the bus represents data information to read from an interrupt controller. External hardware is expected to drive the data during INTA- low, with the same timing as RD-, providing an interrupt vector, either an RST or a CALL instruction. This is in response to an INTR, Interrupt Request, signal.

The first thing to consider in measuring the line voltage of a home wall outlet is the oscilloscope probe voltage rating. Most high-impedance probes have a resistance of one Megohm of greater and will withstand peak voltages in excess of 200 Volts, but it pays to make sure that you do not damage the resistor within the probe.

The next item of concern is the current flowing in the power line ground. If you have a ground current protected outlet, then it will be safe from dangerous ground currents. It will also limit the voltage errors produced by any circulating ground currents. As is the case for many instruments, the metal case is generally tied to the line common through a small capacitor, so the ground current can produce a small voltage between the case and line common. That is the purpose of using a line current interrupter for protection. Do NOT connect the oscilloscope ground lead to the line socket. If you connect it to the wrong pin, then the case can be at a high enough voltage to cause shock. Better to be on the safe side.

Keep in mind that the voltage is rating in RMS (root-mean-square) volts and not peak or average volts. Therefore, the sine wave peak is 1.414 (square root of 2) times the RMS voltage. Conversely, the RMS voltage the peak voltage divided by 1.414.

Resistors have no polarity.

The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).

The easiest way would be to add another potentiometer (of the same rating) in series with the master volume control.

Very careful or not at all, because some of the voltages is extremely HIGH it can vary between 300 VDC for a vacuum tube up to a thousands of volt on a CRT and any DC voltage over 24 volt are LETHAL.

All motors work on magnets dude!!!! so yes magnet motors do work irrespective if they are AC or DC :D!! hope this is what you were looking for

The Fipio Protocol is a standard communication system between different control systems. It can provide high availability and rapid response to safety systems lacking a fail safe.

Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
