Calibration is required to maintain the accuracy and reliability of instruments.
Current transformers are not voltage transformers. Current transformer are used for metering or protection purposes, with single turn primary. Generally the secondary current is either 1Amps or 5Amps.
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.
A mix of a company's long-term debt, specific short-term debt, common equity and preferred equity. The capital structure is how a firm finances its overall operations and growth by using different sources of funds. there are three structures followed by the companies 1.Maturity matching policy - Current liabilities only can finance by the amount of temporary current assets. low risk 2. Aggressive policy - Current liabilities can finance by the amount of temporary current assets and permanent current assets. too risky 3. Conservative approach - Current liabilities only can finance by the a part of amount of temporary current assets. it means temporary current assets> current liabilities. the more safest mode to financing. - AzR 13 -
nickel!
You can deposit nickel as a coating by using nickel chloride and a technique known as electroplating.
In electroplating, a dish is filled with a mixture of water and salt of the metal that is to be used as the coating. The object to be plated, along with a metal bar that is not affected by the bath is immersed into the dish. The object to be coated is connected to the negative terminal of a battery, and the battery is connected to the metal bar. When?æ power is turned on, the electroplating begins to form an alloy on the object to be coated. The longer it is left in the bath, the thicker the coating becomes.
The examples of metals used in electroplating are Chromium and Lead.
For corrosion-resistant surfaces, batteries, and electroplating much as anywhere else.
I believe you're talking about redox electroplating in a salt medium. If that's the case, then nickel is in fact the reducing agent. Reducing agent loses electrons, oxidizing agent gains.
Electroplating is depositing a layer of some other material onto a base by use of electrical current (and ion salts). Anodizing is changing the outer surface of the metal chemically.
The most common way, Electroplating, whether that be Zinc, Nickel or Chromium. Or by using a non-electro immersion process such as EN (electroless nickel), Zinc Phosphate or Manganese Phosphate. Note: Galvanizing (Hot-dipping in molten Zinc) and Electroplating are two totally different things.
Michael Faraday worked out that the thickness of metal electroplating deposits in a certain time depends on the amount of electrical current, the concentration of the solution and the position the metal holds in the 'electrochemical series.'
Electroplating is not a simple one step process. For automtive grills there is usually a first strike of nickel followed by a chromium strike. There are usually 30 microns of nickel and 0.3 microns of chromium.
Cobalt metal is used in electroplating because of its appearance, hardness, and resistance to oxidation. It is alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses. Stellite alloys, containing cobalt, chromium and tungsten, are used for high-speed, heavy-duty, high temperature cutting tools, and for dies in the metal.
Silver, over time, is oxidised by air and loses its shine. Stainless silver is electoplated with nickel (as is stainless steel) to prevent the oxidation. Electroplating involves immersing the silver object in a solution of a nickel salt and applying a negative charge to the silver to attract the positive nickel ions in the solution to form a nickel coating on the silver.
