Abstract
The experiment is about the elements of series and parallel circuits. The laws on series and parallel resistors, as well as the color code for resistors were observed to calculate the total resistance. The proper connection for ammeter and voltmeter was also conducted and the readings for the voltage and current were obtained.
1. Introduction
The objectives of the experiment are to determine the resistance of a resistor based on its color code and to verify the laws on series and parallel resistors, as well as the cells. Some practical applications of these types of circuits are observable in our daily lives. An example of series circuit is the Christmas lights. If any one of the bulbs is missing or burned out, no current will flow and none of the lights will go on. On the other hand, an example of parallel circuits is the wiring system in our houses. If one of the lights burns out, current can still flow through the rest of the lights and appliances.
2. Theory
Total Resistance:
RT=VTIT
Theoretical for series:
RT = R1 + R2
Theoretically for parallel:
RT=11R1+1R2
Internal Resistance of the cell:
r= E-IRI
Color Code for Resistors:
AB X 10c + D
Resistors for Series | Resistors for Parallel | RT = R1 + R2 + R3... | RT = 1R1+ 1R2+ 1R3 | IT = I1 = I2 | IT = I1 + I2 | VT = V1 + V2 | VT = V1 = V2 |
3. Methodology
Activity 1: Series Circuit
Figure1: Experimental Set-up of Series Circuit
The value of the two resistors used for this experiment was determined based on the color code. These are recorded as R1 and R2. The resistors, in series were connected to a dc source. The current and the voltage drop across each resister were measured using an ammeter
