Shunt resistors are commonly used in current measuring devices called “ammeters”. In an ammeter, the shunt resistance is connected in parallel. An ammeter is connected in series with a device or circuit. How Does a Shunt Resistor Work? A shunt resistor has low resistance, offering a path o...
As the intensity of the stimulus increases, so does the frequency of action potentials. On the next page, we'll learn about how nerves communicate with each other. Synaptic Transmission Like wires in your home's electrical system, nerve cells make connections with one another in circuits ...
The basic ingredient of adder circuits is a pair of logic gates, working in parallel, called a half adder, which can do sums no more complex than (wait for it!) 1 + 1 = 2. One example of a half adder looks like this: You feed in two binary numbers you want to add on the ...
When you start charging a capacitor, the current flows freely without any resistance in the very beginning. As the capacitor charges, the resistance increases so that less and less current can flow. When the capacitor is fully charged no more current flows through it: Here’s a simplified gra...
A basic electrical engineering equation called Ohm's law spells out how the three terms relate. Current is equal to the voltage divided by the resistance. It's written like this: I = V/R where I stands for current (measured in amps), V is voltage (measured in volts) and R symbolizes...
LM324 circuits The best learning is doing it. I am slowly learning in anything but when I try to do it I will understand. You may be the same as me. LM324 oscillator circuit LED flasher – Oscillator circuit The two LEDs will wink to alternate between a Red LED and a Green LED. At...
The walls of the blood vessels impede the flow, and the smaller the blood vessel, the more the resistance to flow. Some of the pressure produced by your heart is just for pushing blood through blood vessels. As electrons move through wires, they bump into atoms. This impedes the flow of...
The racket was unbearable, a constant whine of high-pitched fans trying to cool overheating silicon circuits. It is these chips which have made the A.I. revolution possible. In standard computer architecture, a microchip known as a “central processing unit” does most of the work. Coders ...
Parallel Circuits and the Application of Ohm’s Law Review of Power for Series and Parallel Circuits: Electrical power is the measure of work Power is represented by the symbol “P” The unit of power is the Watt (W) Power is additive in any configuration of a resistive circuit—series, ...
Circuit breakers are widely used in various fields of electrical engineering, such as: Power generation: Circuit breakers are used to protect generators from short circuits, overloads, reverse power flow, etc. They also allow for the synchronization and parallel operation of generators. ...
