Using the colored bands on the two resistors at your table, you determine that the two resistances of the resistors are 100 ohms with 20% tolerance and 330 ohms with a 10% tolerance. What would you expect the equivalent resistance of the two resistors to be (including the uncertainty) if they are connected in parallel?

Name: ENGT 3050 Fundamentals of Electricity LAB EXERCISE #3 Series and Parallel Circuits Objectives: The objective of this exercise is to examine Kirchhoff's Voltage and Current Laws. Kirchhoff's Voltage Law (KVL) states, for a closed loop series path the algebraic sum of all the voltages around any closed loop in a circuit is equal to zero. Kirchhoff's Current Law (KCL) states, for a parallel path the total current entering a circuits junction is exactly equal to the total current leaving...

1) [12.5] Complex fraction application. A device called a resistor is used in electronics to oppose the flow of electric current in a circuit. The strength of a resistor is called its resistance and measured in ohms (92). Two resistors of resistance R4 ohms and R2 ohms can be connected in parallel, as shown in this diagram: R1 R2 When...

I am working on my Physics lab report where it was all about Direct Current Measurement and Ohm’s Law. We had 5 different resistors and had to construct different circuits using a power supply, volt-ohm-milliammeter (VOM) and a digital multimeter to get measurements of resistance, voltage, and current. Nominal values of resistance and tolerance Resistor Nominal Resistance (Ohms) Tolerance (Ohms) R1 680 +/- 68 R2 1000 +/- 50 R3 1500 +/- 75 R4 4700 +/- 470 R5 10,000 +/- 500...
