Parallel Circuit With the Three Resistors - Essay Example

Picture lab1 1 Method Make a parallel circuit with the three resistors R1, R2, and R3 and connect them to a power source. Use an Agilent multi-meter or a multi-meter to take measurements. Conclusion From the experiment, resistors R2 and R3 have the same measurements since they are in a parallel circuit. The current passing through the three resistors R1, R2, and R3 is equal because they are in a series circuit. Picture 2 (lab2. 1/4) Aim The aim of the practical was to design a circuit using the NI multisim 13.0 methods and measure the voltage and current in the circuit. After, calculations based on the readings taken were to be done. Picture 3 (lab2. 2/3) Method The three resistors are to be connected in a series circuit using the conducting wires provided. A multi-meter is also to be connected in the circuit. Picture 4 (lab2. 3/6) Method Theory Two resistors R2 and R3 are to be connected a parallel and resistor R1 connected in series in the same circuit. A multi-meter is then connected appropriately to get the readings of the three resistors. Picture 5 (lab2. 4/7) Five resistors are to be connected in the same circuit but in different arrangements. R1 and R5 are to be in series while R2, R3, and R4 are to be connected in parallel. The readings are then to be taken using a multi-meter. Picture 6 (lab2. 5/8) Resistors in circuit one had all currents through the same because they were connected in series. In a series connection, voltage is divided among all the components. Resistors in circuit two had equal voltage through them because they were in a parallel connection. This is because current flowing through them is the same. In circuit three, R2 and R3 were in parallel hence equal voltage through them. The last circuit four had had R1 and R5 resistors in a series arrangement hence equal current through them. Picture 7 (lab3. 1/9) Aim The aim of this practical session was to study signals. Various types of signals were to be generated and visualized at the same time in a multisim virtual environment. Picture 8 (lab3. 2/10) Method Using connecting wires, the output of the function generator was to be connected to an oscillator’s input channel one. Using the Agilent function generator, the frequency and amplitude was measured. Conclusion From the experiment’s results, the function generator produced square waves. It displayed in the form of waves as seen in the oscilloscope. The wave measured 3Vpp and 1.0 KHz and had the shape of a saw tooth. Picture 9 (lab4. 1/11) Aim The experiment’s aim was to make a voltage divider in the multisim. The voltage divider was to equally divide circuit one into two parts. Circuits two and three were to be divided into three and four parts respectively. Method The two resistors are to be connected with a power source and a multi-meter. The multi-meter would then provide measurements of the current passing through them. Picture10 (lab4. 2/12) Method Three resistors are connected using wires and onto a power supply. A multi-meter is then connected to measure the voltage of the resistors. Picture11 (lab4. 3/13) Method Use wires to connect four resistors with a controlled power supply. Connect a multi-meter to the circuit then measure the voltage through the 4 resistors. Conclusion In the first circuit, currents I1 and I2 were equal. Vi1 and V2 were also equal since the connection was series. In circuit two, the voltage divider we designed divided the voltage of 12v three times and verified that by measuring with a multi-meter. In circuit three, we again verified that the voltage divider had divided the 12v. Picture12 (lab5. 1/15) Method Use the wires provided to connect the three resistors provided and connect them to a power source. Determine the current and voltage through each of them with the help of a multi-meter. Picture13 (lab5. 2/16) Method Connect the five resistors using the wires provided and connect the circuit to a source of power. Use a multi-meter to measure the current flowing through them. Picture14 (lab5. 3/17) Method Make a circuit with the wires provided and connect them to a source of power. Use the multi-meter provided to measure the voltage and current passing through the resistors. Conclusion In circuit one, we determined the voltages Va, Vb, Vc Vac, and Vbc using readings from the multi-meter. The current I2 and source current Is3 were also determined. In circuit two, current through the 10Ω resistor was also determined. In the last circuit three, a nodal analysis was applied in the circuit.

Picture17 (lab7. 2/16) Conclusion Based on the experiment’s objectives, we used the multi-meter to measure to measure the readings of the resistors. The resistors gave varying results. The results were; R1=981, r2=978, R3=984, and R4=1.195. There was no significant difference between those results and that of the simulated software.
