Description :

Resistors capacitors and inductors the three basic elements used in electronic circuits are the resistor capacitor and inductor they each play an important role in how an electronic circuit behaves they also have their own standard symbols and units of measurement. Summary the basic components of a simple circuit are a source of voltage or potential difference v like a battery power supply solar cell etc a device with a resistance r like a light heater motor television etc identified by the generic name resistor wires of negligible resistance to carry current i on a closed loop from the voltage source to the resistor and back. In a nutshell resistors dissipate energy and capacitors store energy to understand the nature of circuits which include capacitors one ideally should have an understanding of current as a function of time in a circuit and how the flow of current leads to the build up of charge. Kirchhoffs laws for current and voltage lie at the heart of circuit analysis with these two laws plus the equations for individual component resistor capacitor inductor we have the basic tool set we need to start analyzing circuits this article assumes you are familiar with the definitions of node distributed node branch and loop
