A simple ohmmeter is made by connecting a 2.50 V battery in series with a resistance R and an ammeter that reads from 0 to 1.00 mA, as shown in the figure. Resistance R is adjusted so that when the clip leads are shorted together, the meter deflects to its full-scale value of 1.00 mA. What external resistance across the leads results in a deflection of (a) 11.3%, (b) 54.3%, and (c) 92.6% of full scale? (d) If the ammeter has a resistance of 18.8 Ω and the internal resistance of the battery is negligible, what is the value of R? (a) Number Units (b) Number Units (c) Number Units (d) Number Units
