Squish circuits bridge the gap between professional engineers and young, aspiring, minds. One of the Perot Museum’s main concepts is exposure; Squishy Circuits provides children, who normally wouldn’t be exposed to electrical engineering in school, a chance to broaden their horizons. Squishy circuits, utilizes Play-Doh-like-clay as conductors and insulators in order to build small circuits. Using something familiar like clay, allows kids to easily grasp the concept. It also allows for people of all age groups to be able to expand their knowledge of electrical engineering with varying levels of complication. The patrons can make circuits with LED lights, motors, buzzers, and much more.

In the present generation, almost every devices run through batteries. Batteries are a collection of cells where their chemical reactions create a flow of electricity in a circuit. Every battery consists of three essential components, which are an anode, a cathode, and an electrolyte that chemically reacts with the other two components. In the 17th and 18th century, electricity was just a curiosity, but as time passed by, it became one of the most important and required tools. For instance, any kind of remotes in order to have an access to any kind of devices requires batteries. Alessandro Volta was the one to make the crucial invention that caused the transformation in our lives. Our lives wouldn’t be like now, with no laptops, phones, and

Without getting too technical, electricity is the result of a chemical reaction. As a Berkeley teacher’s guide to this experiment demonstrates, the penny is copper, while the galvanized nail is coated in zinc. When zinc, which is negatively charged, comes into contact with an acid, electrons are freed in a chemical reaction. Copper, which is positively charged, accepts those electrons, thereby creating an electric circuit.

A battery has three main parts: it has two terminals made of chemicals, which are called the anode and the cathode. There’s also the electrolyte, which detaches the two terminals. The electrolyte is a chemical medium. It allows the flow of electrical charge between the cathode and anode and when a device is connected to a battery the chemical on the anode releases electrons to the negative terminal. This is called an oxidation reaction. While this is happening, at the positive terminal the cathode accepts electrons. This completes the circuit for the flow of

This one had red wires which transmitted current to two LEDs in parallel in order to light them up. Each LED had two 220Ω resistors through which the current exited the LED and green wires that led the current to ground. After calculating this circuit’s values, we used both the resistance equation and Ohm’s Law the same way we had for the first circuit (separating the two LEDs into different circuits and for Ohm’s Law using only the current which passed through the branch). This gave us 106Ω as the resistance of the red LED and 107Ω as the resistance of the green

Basically it is a sensing device by which a physical, mechanical or optical quantity to be measured is transformed directly into an electrical signal (such as current, voltage and frequency) with a suitable mechanism,. The production of these signals is based upon electrical effects which may be resistive, inductive, capacitive etc. in nature. The input versus output energy relationship takes a definite reproducible function. The output to input and the output to time behavior are predictable to a known degree of accuracy, sensitivity and response, within the specified environmental conditions. Modern digital computers have made use of electrical transducers absolutely

In two articles, "Energy Story" and "Conducting Solutions", I learned about electrical charges, ions, conducting energy, and what atoms are like when they are broken down. In a video, Hands-On Science with Squishy Circuits, I learned about conducting electricity using simple things, which, in this case, was Play-doh. One thing these two articles and this video share in common are that they all have something to do with energy and electricity.

Ans: Electricity is the movement of electrons. As long as electrons in an atom are balance and revolve precisely in orbit around their sun or atom nucleus there is no electron flow or electric current in a wire. These atoms are the smallest particle into which an element can be divided without losing its property. A single atom consists of three basic components: a Proton, a Neutron and an Electron. An atom is similar to a small solar system, so is the nucleus in the centre of an atom. Protons and neutrons are contained within the nucleus. Electrons orbit around the nucleus which could be similar to planets orbiting around the sun. As an electrician I will also be

To determine the effect that the voltage will have on the current of a circuit, when one resistor is connected in the circuit.

An incorporated circuit or solid coordinated circuit (additionally alluded to as an IC, a chip, or a microchip) is a situated of electronic circuits on one little plate ("chip") of semiconductor material, typically silicon. This could be made much more diminutive than a discrete circuit produced using free segments. Ics could be made exceptionally minimal, having up to a few billion transistors and other electronic segments in a range the span of a fingernail. The width of each one directing line in a circuit might be made littler and more diminutive as the innovation propels; in 2008 it dropped beneath 100 nanometer, and now it is many nanometer.

After measuring the given resistor, the power supply was connected in series to the DMM as an ammeter and the 100-ohm resistor. Next, the second DMM as a
