What is Equivalent Resistance?The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network. Equivalent resistance may sound complicated, but it’s just a technical way to say “total resistance”.In the equivalent resistance of a network, a single resistor could substitute the complete network so that

What is Electric Current?Electric current is defined as a stream of charged particles—such as electrons or ions—moving through an electrical conductor or space. It is the flow rate of electric charge through a conducting medium with respect to time. Electric current is expressed mathematically (e.g. in formulas) using the symbol “I” or “i”. The unit for current is is ampere or amp. This is represented by A.Mathematically, the flow rate of charge with respect to time can be expressed as,In other

What is Voltage?Voltage (also known as electric potential difference, electromotive force emf, electric pressure, or electric tension) is defined as the electric potential difference per unit charge between two points in an electric field. Voltage is expressed mathematically (i.e. in formulas) using the symbol “V” or “E”.If you’re looking for a more intuitive explanation to help explain what voltage is, skip to this section of the article.Otherwise, we’ll continue below with a more formal defini
