Capacitors are passive two terminals electronic components that store energy in form of electrical field. Practical capacitors contain at least two electrical conductors (plates) separated by a dielectric that is; insulator. The conductors can be thin “non-conducting”. Dielectric acts to increase the capacitance. That is; capacitor’s ability to store charge. A dielectric can however be …

Determining Unknown Resistors Values

You might have often come across Resistors and wondered, tried to figure out its value and asked yourself “what is the value of this resistor?” You become frustrated to determining unknown resistors’ values. Perhaps on a Printed Circuit Boards (PCBs), you might have seen a resistor soldered and with its value written on the board.  …

Read Resistor Colour Codes

Resistors colour codes system of determining unknown resistor’s value could be hard to be used. But in this post I published, “How to Read Resistor colour codes” makes things easy and simple. Resistors which their values are not printed on them use colour codes for their resistance identification. This article on resistor colour codes teaches …

State Ohms Law and its Limitations

At the end of this post, you should be able to state ohms law and its limitations respectively. OHM’S LAW A German Physicist George Simon Ohm in 1926 made an experiment and observed that for any good conductor, there is a relationship between current (I) flowing through the conductor and the potential difference (V) across …

Short circuit and its meaning

Short circuit and its meaning

A short circuit is the state in which current flows back to its potential source directly. It happens sometimes when the power supply lines contact each other directly. Also, conducting materials of a very low or negligible resistance in parallel to the potential source can cause short circuit too. A circuit diagram below this post …
