3. Measure the resistance across each resistor and across the entire circuit to verify your calculations. Due to the large resistance values and tolerances of the resistors, your measurements and calculations may not exactly agree. Touch the resistors only with the metal tips of the probes/leads – your fingers may influence the readings due to the high resistance of the circuit.
4. Ohm's Law Verification – Measure and record the voltage across each resistor. Explain Kirchhoff's Loop (Second) Rule. What are the loops present in this circuit?
5. Kirchhoff's Junction (First) Rule states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction. Identify the junction(s) in your circuit either in words or in a drawing/sketch.
6. Using Ohm's Law, determine what the currents should be in your circuit. Measure the current between R1 and the battery (total current) by breaking the circuit (either pulling the wire out of the breadboard or pulling one end of the resistor out of the breadboard). You will have to touch or hold the wire onto the metal tips of the probe/leads to take the measurement. You will also need to use the lower setting on your multimeter (200 µA) to measure the current. Attempt to measure the current through one of the resistors in parallel. Does this agree with your calculations, why or why not?
7. And finally, design a circuit not previously built, using at least three components in your kit. It must be a complete circuit. Take a digital picture of your design and include it below. Measure voltages around your circuit to verify Kirchhoff's Loop Rule.
