Consider the icosahedral resistance network shown in the following figure. Each edge is made of a rod of resistance $r$. Select the option(s) that is(are) correct:

icosahedron

A) The resistance between points A and B is $\frac{r}{2}$
B) The resistance between points A and B is $\frac …

An Interesting Electronics Problem

Posted on Wed 29 April 2020 in Electronics

An interesting electronics problem I encountered recently was this: Find the resistance between points A and B in the following resistor network

resistor network

This looks like a simple wheatstone bridge problem, but note that the top right and bottom left resistances are R and not r. To solve this problem, we'll …

Electronic Clock II - Generating the Clock Signal pt. 2

Posted on Sat 16 June 2018 in Electronics

In the previous post, we saw how to make a 2Hz clock signal. However, for the seconds counter, we will need a 1Hz clock signal. In order to achieve this, I will clock down the frequency using a JK Flip Flop:

Flip-Flop: Concept

A Flip flop is a one-bit storage …
