Picture lab1 1) Methods Connect the conducting wires making the circuit to the source of power. Insert three resistors R1, R2, and R3 in the circuit, but on a parallel arrangement. With the help of a multi-meter and Agilent multi-meter, take the resistors readings for use in calculations later. Conclusion The experiment shows R2 and R3 have equal resistance since they are placed in a parallel arrangement. Currents recorded at resistors R1, R2, and R3 are equal because they are arranged in series. Picture 2(lab2. 1/4) Aim The experiment’s core aim is to design a circuit following NI Multisim 13.0 model and measure the current and voltage as directed the circuit diagram provided.

Picture 4 (lab2. 3/6) Method Theory Resistors R2 and R3 are to be connected in parallel and the third, R1 in series. The values of R1, R2, and R3 are then to be taken using a multi-meter. Picture 5(lab2. 4/7) Method You are provided with five resistor; R1, R2, R3, R4, and R5. In the circuit, connect R1 and R5 in series, and R2, R3, and R4 in parallel. Picture 6 (lab2. 5/8) Conclusion Current through all resistors in the first circuit was the same. It was because they were in a series connection where they share voltage equally. Circuit 2 had the same voltage through all the resistors because they were connected parallel to each other. Circuit 3 had equal voltage in R2 and R3 because they were connected in parallel. In circuit four, current through resistors R1 and R5 was the same because they were connected in parallel.
