The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.[1] It is named after the Italian physicist Alessandro Volta.

Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as “electric potential”, which then must be distinguished from electric potential energy by noting that the “potential” is a “per-unit-charge” quantity.

The ampere, often shortened to “amp”, is the base unit of electric current in the International System of Units.

Tungsten, or wolfram, is a chemical element with symbol W and atomic number 74.

It is well known that elements with a higher atomic mass then to have higher melting points. For Tungsten there is the added indication that some of its valence electrons (the 5d electrons) are making covalent bonds between neighboring atoms in the bcc crystal structure. So melting temperature will be high.

There are many types of resistors, both fixed and variable. The most common type for electronics use is the carbon resistor. They are made in different physical sizes with power dissipation limits commonly from 1 watt down to 1/8 watt. The resistance value and tolerance can be determined from the standard resistor color code.

Thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices.

The equivalent star resistance connected to a given terminal, is equal to the product of the two delta resistances connected to the same terminal divided by the sum of the delta connected resistances.
If the delta connected system has the same resistance R at its three sides then equivalent star resistance r will be,

  1. all parallel.
  2. all series.
  3. 2 series and one parallel to one.
  4. 2 series and one parallel to other two.

Interference occurs when unwanted radio frequency signals disrupt the use of your television, radio or cordless telephone. Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment.

suppression capacitors are used to suppress any noise from an electronic device by reducing the input impedance of the device.

If you curl the fingers of your right hand in the direction of the circular component of the current your right thumb points to the north pole.
