What is an Electric Circuit? An Electric Circuit is a closed path for transmitting an electric current through the medium of electrical and magnetic fields. The flow of electrons across the loop constitutes the electric current. Electrons enter the circuit through the ‘Source’ which can be a battery or a generator. The source provides energy […]

Frequency Divider Circuit using 555 and 4017
In this project, I will design a simple Frequency Divider Circuit using 555 Timer IC and CD4017 Counter IC. What is Frequency Divider? A Frequency Divider is a circuit that divides a given frequency by a factor of n, where n is an integer. For example, if the frequency of the Input signal to […]
Types of Errors in Measurement
What is Measurement? Representing quantities of various attributes relating to a real time system, using numerical values, is known as Measurement. It can be realized as a comparison between the quantity of unknown magnitude and a predefined standard. The main requirements for accurate measurements are Apparatus should be accurate. The method used ought to […]
