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.

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

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

DC circuit analysis and design, play a massive role in electrical engineering and without the correct application of theory and practise in unison, nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability to analysis a circuit gives a potential electrical engineer the ability to learn how to problem solve in a theoretical and practical sense which in turn develops industry skills in which will follow them for life, and allow a solid knowledge base

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.

Once the experiment was complete and the data was collected and graphed, it was shown a trend was established; that an increase in current would lead to an increase in voltage. Another similarity in the data was that as the amount of batteries increased, the voltage and current in the circuit also increased. This is because as more energy is added to the circuit, the amount of energy per charge increases (voltage), therefore increasing the amount of charge in one part of the circuit in one second (current). Two of the resistors used in the circuits were very similar both in data points as well as their corresponding resistance calculations. However, one of the resistors was different.

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.

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.

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

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
