For measuring high inductance like 100H, the bridge we use is: James Clerk Maxwell Bridge which people also call Maxwell Inductance-Capacitance Bridge. It is made for medium to high Q inductors but when the inductance is large then it still behaves nicely, so people mostly prefer this one. Audio/Video Representation Basic Concept Basic idea of […]

How to Measure Transformer’s Current Capacity
We can use a shunt resistor and ammeter concept to find out how much maximum current a transformer can give, in other words, we are trying to know the current rating or amp capacity of a transformer. If you do not wish to read the full article below, you can feel free to watch the […]
Arduino Frequency Meter Using 16 x 2 Display
In this article I will show how to construct a digital frequency meter using Arduino whose readings will be showcased on a 16 x 2 LCD display and will have a measuring range from 35 Hz to 1MHz. Introduction Being electronics enthusiast, we all would have come across a point where we need to measure […]
Digital Capacitance Meter Circuit Using Arduino
In this post I will show how to construct a digital capacitance meter circuit using Arduino which can measure capacitance of capacitors ranging from 1 microfarad to 4000 microfarad with reasonable accuracy. Introduction We measure value of the capacitors when the values written on the capacitor’s body is not legible, or to find the value […]
Making a Single Channel Oscilloscope using Arduino
In this interesting post, we are going to make a simple single channel oscilloscope using Arduino and a personal computer, where the waveforms will be showcased on the PC’s display and frequency and time period of the input waves will be displayed on the 16 x 2 display. Introduction Every electronics enthusiast once said “I […]
Arduino based DC Voltmeter Circuit – Construction Details and Testing
In this post, I will show how to construct a DC voltmeter using Arduino where the readings are displayed in 16×2 LCD. The proposed voltmeter design can read up to 30V with tolerance of +/- 0.5 volt. We are going to see how this setup functions and explore other possibilities we can accomplish other than […]
