Ohm's law

engineering profession on Shadow-an-Engineer-Day on October 17, 2016. For the Circuit Lab, I was asked to use concepts of Ohm’s Law and read/analyze circuit diagrams with common components, then test them on a breadboard. The purpose of this lab report is to provide information on the setup and procedures for circuit 1 and the calculations/analyses for all five circuits. Summary For the Circuit Lab, I was asked to perform various…

to test whether the copper wire will have less Resistivity (ρ) than the iron wire, and/or the two copper wires connected together. Resistivity is defined as how strongly a particular material resists current, and is measured in Ohm-meters (Ω-m). Electrical resistance (R) is the opposite of the flow of electrons, or the passage of an electrical current. Electrical conductivity (σ) is the opposite of resistivity and is measured in Siemens (S). Electrical conductivity is defined as; the degree to…

6/10/2015 Mrs Rummins | GRUJICIC, Marko Background: Another name for I/V characteristics is current-voltage. Current and voltage are the factors that are being investigated, there characteristics and effects in diodes of different colours. The Current or I in I/V characteristics refers to the flow of an electric charge. It is often carried out by electrons when moving through wires Materials: -green, red, blue, yellow coloured diodes -breadboard -wires - 2X multimeters, 1 as a voltmeter…

5. RESULTS Lightning effect is generated using the Heidler block. The lightning of 100 kA will strike on the shielding wire in case of mitigation due to shielding and on phase A in case where surge arresters are considered. Below is a figure of a 100 kA lightning strike. This current is measured at the node where the lightning strikes. Fig. 5.1 Lightning strike current of 100 kA When lightning strikes on the shielding conductors the current induces a voltage on the phase conductors. Here we…

The resistors R1, R2, RD, and RS calculated in the Prelab section were used to connect the circuit as shown in Figure 8-5. A load resistance RL of 10kΩ was used. The values of VD, VG, VS were measured and recorded. 3. The voltage vout was measured using an oscilloscope and the voltage gain AVG-D = vout/vin was calculated. The input voltage was adjusted if the output waveform was distorted. 4. The function generator was varied to obtain the necessary data to plot a frequency response curve for…

The first part of the experiment was determining the resolution of the DAC in volts. Before a voltage was applied the noise was determined by measuring the DC offset, the reading of the DMM at an input of zero volts. This offset was removed from the recorded values in order to provide a more accurate reading of the resolution. These corrected values and their corresponding applied voltages can be found in Table 1 of the appendix. The lowest value recorded from the DMM was -9.968V and the…

in each resistor, the sum of the resistors is the total resistance of that circuit. To find out the current that flows through a DC series circuit you must first remember that current flowing through this type of circuit does not change. Therefore, a simple way of calculating current can be used by implementing “ohms law”. Ohms law tells us that Voltage (E) is equal to the current (I) multiplied by the resistance (R). So by using simple math we can swap the variables “E=I*R” into “I=E/R” to…

For part A, a graph plotting the charge over the capacitance was created and the slope identifying the experimental voltage was found to be 4.74 V. A discrepancy of 5% was found by using the discrepancy formula D=(exp/th-1)×100% with a theoretical voltage of 5.0 V. In addition, the graph plotting the charge over the voltage was created and the slope identifying the experimental capacitance was found to be 0.95 μF. A discrepancy of 5% was found using the discrepancy formula with a theoretical…

Ohm’s law is the basic rule of the electricity that explains the relationship between electric current, voltage, and resistance. The ohm’s law was named after the German physicist Georg Ohm who discovered this rule or law. Ohm’s law statement Ohm’s law states that the electric current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance. In other words, the electric current flowing through the conductor increases with increase in…
