What does P stand for in electrical?

Definition. Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially to mean "electric power in watts."

What is current PP?

It means peak-to-peak voltages or currents. Those displays are multiplexed so the grids and anodes are fed with square waveforms so their peak voltage or current is more important than for example the heater voltage/current which is given just in RMS voltages.

What is the meaning of J and P fuse?

By Media Nigeria on May 12, 2018 2 Comments. Power fuses are a generally accepted means of protecting power transformers in distribution substations.

What letter are used for electrical current?

1 Answer. The letter 'A' (Ampere or Amps) is used as an abbreviation for electric current.

What does pp mean on a AC?

AC Voltage Terms

Peak-to-Peak Voltage (V_PP) The full voltage between positive and negative peaks of the waveform; that is, the sum of the magnitude of the positive and negative peaks.

Part P

What does PP support mean?

pp. UK (also p.p.) written abbreviation used to show when someone has signed a document for a person who is not available to sign it: I hope to hear from you soon.

What does PP material mean?

Polypropylene (PP) is one of the most commonly used thermoplastics in the world. Polypropylene uses range from plastic packaging, plastic parts for machinery and equipment and even fibres and textiles.

What does PE stand for in electrical engineering?

PE - Protective Earth. In the UK, they call it "earthing". In the US, we call it "grounding". They mean the same electrical 0v potential. The purpose of PE is to protect against electric shock and fire due to leakage current.

What do the letters mean on a circuit breaker?

The first letter stands for the frame type of the breaker. If it's F, it has a rating capacity of 15 to 100 amps. Other frame types include M (300-1000 Amp), L (125-400 Amp), and K (70-250 Amp). The second letter stands for its interruption rating, or how many amperes it can take before it trips.

What are the symbols used in electricity?

What does pp size mean?

PP (double-petite) P (petite)

What does pp mean in cars?

Every car is a different weight, and boasts different levels of engine power. As a result, every car in Gran Turismo 6 has been given a PP (Performance Points) figure, which indicates its performance level.

What is symbol for current?

Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R.

What are the 4 basic units of electricity?

Therefore, the 4 basic units of electricity are volts, amps, ohms, and watts.

What is m in electrical?

Motor. A motor, shown as a circle with the letter M inside it, changes electricity into movement.

Which fuse is used in transformer?

Glass tube fuses are perhaps the most common type of fuse. They come in several sizes and are used widely. Miniature circuit-breakers come with both ther-mal cha- racteristics and current characteristics, or a combination of the two.

What are the types of fuse?

What are the 6 most common symbols used for an electrical schematic diagram?

What is the symbol of connecting wire?

1 Answer. A connecting wire is represented by a straight line.

How are breakers numbered?

In a U.S.-style board, breaker positions are numbered left-to-right, along each row from top to bottom. This numbering system is universal with numerous competitive manufacturers of breaker panels.
