Electrical Frequency, Power, Voltage, Current Symbol


Electrical Frequency, Power, Voltage, Current Symbol



In electrical and electronics engineering, electric current, voltage, power, and frequency are the most important and basic terms. If you want to strengthen your theoretical as well as practical knowledge, then you must have a clear idea about these basic terms. In this article, we are going to see the symbol of these terms.


Electric Current Symbol


Electric current is the flow of electrons through a conductor. When a potential difference or voltage is applied across a conductor, the current will start flowing from the higher potential to the lower potential. Actually, this flowing of electric current does the useful works. Here, you can see the symbol of current.

electric current symbol, symbol of current



The theoretical symbol of electric current is denoted by the English letter 'I'. All theoretical data, mathematical calculations use this symbol.


DC or Direct Current Symbol


According to the nature of polarity and magnitude with time, electric current is classified into two types - alternating current and direct current. Direct Current or DC does not have any polarity and has a constant magnitude. Here, you can see the symbol of direct current.

DC or Direct Current Symbol, symbol of direct current


The symbol of direct current is denoted by a straight line, which indicates its constant polarity and magnitude.




AC or Alternating Current Symbol


Alternating current has changing polarity and magnitude with time. This magnitude and polarity depend upon the frequency of the power supply. Here, you can see the symbol of alternating current.

Voltage Symbol


Voltage is the electric pressure or potential difference across a conductor that force to flow the electric current. Here, you can see the symbol of voltage.

Voltage Symbol, symbol of voltage


Electric voltage is denoted by English letter 'V'. In theory, this symbol is used for all the calculations.


Power Symbol


Electric power is the combination of voltage and current consumed by a load or delivered by a power source. Here, you can see the symbol of power. It is denoted by the English letter 'P'

Practical Symbol of Power


Here, you can see the standard practical symbol of power. this symbol is used with power ON/OFF switches, power buttons, etc.

Frequency Symbol


The term 'Frequency' indicates that ho many times the polarity of alternating current changes per second. Here, you can see the symbol of frequency. It is denoted by the English letter 'F'.
