Question
(5 should say: solve for the unknown, out of range C2) 3. Suppose you were given the task of measuring the capacitance of an unknown device. The capacitance of this device is very small, so even when your meter is on its lowest possible setting your display shows the following (in nF): Design a procedure to measure Cuk despite it being below scale. 1. Apply Theorem_' because 2. Measure the known capacitance C. 3. On a breadboard, connect the capacitors C and Ck in 4. Now, measure 5. Now, considering the meter resolution, sig fig rules, and rounding-off rules, would this method work? Answer by supposing that you are given two capacitors whose exact values are C= 1.0325 nF and C.-0.00022 nF, then applying your method.Explanation / Answer
1. Apply Theorem 1 , because in parallel combination effective capacitance is greater than larger capacitance, this would bring the value into the range of meter.
2.
3. Parallel
4 . Measure effective capacitance
5. C2 = Ceq - C1
Our method would work if the meter resolution is of the order of 0.00001 nF. if the resolution is less than that our method would not work, as the value of the unknown capacitor would be rounded off in approximation
