Ohm 's Law & Series Circuits

What are some of the basic components that make up simple circuits and what do they do?

In this video, AnnMarie Thomas shows how two different types of homemade playdough can help you change your students or children into circuit designers. You make on batch of playdough using salt, and then another substituting salt with sugar. First, you take a battery pack, and plug the two wires into two separate pieces of playdough containing salt, or the positive playdough. You can then stick a tiny LED light into the playdough, and it will light up, but when the two positive doughs are pushed together, you create a short in the circuits. This happens because the electricity wants to run through the two positive doughs, not one positive dough. To prevent this from happening, you take a piece of the sugary dough you made, or the negative dough, and place a clump of that in between to two positive doughs. However, the sugary dough is 150 times more resistant to electricity than the salty dough, due to the ions in the sodium chloride in the salty dough. The sugary dough then creates a barrier, successfully making a functioning

kindly find below the information for this meters and we will take the reading next week to check and compare between analog and digital meters to get final result

T= 40ms, I figured this by guessing cause I could not find any information on how to calculate. So I used the equation for t and plugged in different numbers until I got the 10ms that was already given in the table. t= T x 0/360= 40ms x 90/360= 0.01 x 10^-3= 10ms

In Lab 8, the time constant of resistance-capacitance was measured in order to determine the charge of a capacitor. This experiment was conducted by setting building a circuit that connects the voltmeter across the resistor. The voltmeter was then connected across the capacitor. The above procedure was conducted several times using different voltages. Afterwards, the results were calculated and tabulated. The data obtained from the lab were the theoretical Tau for 5V, 4V and 3V. In this experiment, the calculated voltage was also determined. The theoretical and the calculated values were then compared and evaluated by determining their percentage errors. For example, in the 5V, the theoretical value was 1.23V; calculated value was 1.434 with a percentage error of 16.6 %( for voltmeter across capacitor).

The two types of electrical circuits are series and parallel. Series circuits provide only one pathway of current flow, while parallel circuits provide multiple pathways of current flow. Unfortunately,

6) Change the location of the positive charge to at least six widely different distances from the equipotential sensor. Record the voltage reading and distance at each location.

The variables been shown in the simulater are the voltage, current, and ressistance. V(volts) = I(Ampers)* R(Ohms).

By first measuring the pH levels of solution A through E with a pH meter, it gives a numeric reading to ph balance to a solution. Next, add in a natural indicator called anthocyanin made from the pigment from a red cabbage into each solution and mixed it until there is a distinct color and recorded on the chart. Finally, by looking at the result of the pH reading level that

The diagram below shows a labelled circuit which is used for the experiment. This is set up by collecting all equipment needed and attaching the DC power supply to the ammeter with a wire this is all connected to the anode and cathode with a red and black wire to differentiate between the two electrodes. The two electrodes are shown to be placed in a beaker of copper sulphate

The circuit (above) shows how we set up the circuit for our preliminary work and our experiments. In our preliminary work, we used some constantan wire in a circuit like above and used it to see what voltage is best to keep the same to find the current and resistance. We found that 3 volts was a good voltage because the current not too high or too low to get a good resistance.

Throughout this experiment we looked at basic principles of DC circuits and electrical currents by measuring the voltages and currents in simple currents. We used Ohm’s law R=V/I and R=E/I and the values of current and voltage to find the resistance of an electric circuit. We also found that the SI unit of volt are Joules/Coulomb and that power is measured in Watts.

After obtaining the engineering requirements for the wire, six samples were sent to the lab to be tested.

The sounding survey was performed using a Schlumberger array. Two measuring tapes were rolled out in opposite directions from a fixed centre point, to ensure accurate measurements of both the voltage and current electrode spacing’s.

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl
