Document Summary
Vi(1) the goal of this experiment was to become familiar with the wheatstone bridge and use it to determine resistance using both ac and dc techniques as well as to determine capacitance. To do this we assembled a circuit which included a. Wheatstone bridge, two resistors and a battery source. Vi(2) in this section we switched from a dc power supply to an ac power source and did the same readings. 2)) l = 147 ((1/50) + (50/502)) (0. 01) = 0. 0588. Rm lies in the range determined by rx. All other resistor readings lie outside this range. This could be due to human error or a miscalculation in l. This section has the same results for rx as the last. Vi(3) for this section we assembled a circuit with capacitors and measured directly the capacitance. Least decimal of answer is same power of 10 as uncertainty. Cm lies in the range determined by cx.
