gh the known resistance is 6.28 voltsand through the unknown 2.25, what is the unknown resistance if theknown is 3.5 ohms ? Ans. 1.254 ohms. 2508. Another way to attain the same result would beto connect the known and the unknown resistance in parallel,and measure the currentin each. The… … ELECTRICAL MEASUREMENTS. 1637 resistance cd. Ammeter A M measures the current \n ahand ammeter A^ M^ measures the current in c d. It is to be noted that the ammeters and their connectingwires should be of such low resistance as not to add mate-rially to the resistance of either branch of the…
