HS-PHY102 – GENERAL PHYSICS 2

Second Semester, S. 2019 – 2020 WORKSHEET NO. 4

Name: AGUILAR, R. & PANGANIBAN, N. Date: APRIL 22, 2020 Grade & Section: 12-ANDRES Score: ________________________

Resistor Color Code

Directions: Practice “reading” and converting resistor color codes to their numeric equivalent and vice-versa. 1. For each set of color bands, indicate the nominal resistance value based on the first three colors of the color code and then use the fourth (tolerance) band to determine the minimum and maximum value of each. 2. In the problems where the numerical values are given, work “backwards” to determine the color code. In general, use the closest favored metric abbreviation to report your answer. Tolerances: Red = 2%; Gold = 5%; Silver = 10%; No fourth band = 20% Color Bands Nominal Resistance Value

Minimum Value Maximum Value

Example: Red, Blue, Red, Gold

2 Ω 2 Ω 2 Ω

1. Brown, Blue, Orange 16k Ω 12 Ω 19 Ω 2. Gray, Green, Black, Gold 85 Ω 80 Ω 89 Ω 3. Blue, Gray, Red 6 kΩ 5 Ω 8 Ω 4. Violet, Red, Brown, Silver 720 Ω 648 Ω 792 5. Red, Brown, Gray, Red 2 Ω 2 Ω 2 Ω

Resistors in Series and Parallel

Directions: Read and analyze each problem carefully, then solve. Verify the given answer/s for each item by showing your complete solution. Do not forget to box your final answer. (10 points each)

NO SOLUTIONS= NO CREDITS!!

  1. Three resistors having resistances of 1 Ω, 2 Ω, and 4 Ω are connected in parallel to a 2 V battery that has negligible internal resistance. Find a.) the equivalent resistance of the combination; b.) the current in each resistor; c.) the total current through the battery; d.) the voltage across each resistor.

  2. Compute the equivalent resistance of the network shown in the figure and find the current in each resistor.

NO SOLUTIONS= NO CREDITS!!
1. Three resistors having resistances of 1.60 Ω, 2.40 Ω, and 4.80 Ω are connected in parallel to a 2.80 V
battery that has negligible internal resistance. Find a.) the equivalent resistance of the combination; b.)
the current in each resistor; c.) the total current through the battery; d.) the voltage across each resistor.
