PHY 132 DC Circuits Name: Salaheddin Ahmadi Section: 17084 Group #: 3 TA: Malkiyat Singh 2/22/2017 Abstract: It was discovered that light bulbs shine brighter in parallel configuration in oppose to series. Resistance of three resistors provided were calculated using color code technique and they turned out to be 15, 39, and 47 Ohms for R1, R2, and R3 resistors respectively. Resistors R1 and R2 were connected in series; the equivalent resistance of circuit was measured as 58.5 Ohms compared to calculated 60.5 Ohms. It was concluded that sum of the potential difference of each individual resistor in series is equal to the potential difference of the total circuit.
When resistors were connected in parallel the equivalent resistance of the entire circuit was measured as 12.87 Ohms compared to 13 Ohms calculated. The current passing through R1 and R2 was measures as 0.139A and 0.065A respectively. It was concluded that sum of currents in each branch of parallel circuit equals the total current of the circuit which was 0.202A. The equivalent resistance of the combination of parallel and series circuit was calculated as 40.66 Ohms compared to 40.5 Ohms measured. Experimental Data: Part 2: Color code value of resistance Resistor Colors Resistance Percentage R1 Brown, Green, Black, Silver 15 10 R2 Orange, White, Black, Gold 39 5 R3
