Here is the pblm, but i can't seem to get a foothold as where to start. I've tried starting with Kirchov's Laws, but can't see to get anywhere with them. Plz help.(adsbygoogle = window.adsbygoogle || []).push({});

*One type of ohmmeter consists of an ammeter connected to a series resistor and a battery. The scale is different from ammeters and voltmeters. Zero resistance correspodns to full-scale deflection (because maximum current flows from the battery), whereas infinite resistance corresponds to no deflection (no current flow). Suppose a 3.0V battery is used, and a glavanometer that has an internal resistance of 25ohms and deflects full-scale for a current of 35 microAmps. What values of shunt resistance, R(shunt), and series resistance, R(series), are needed to make an ohmmeter that registers a mid-mid scale deflection( that is half the max) for a resistance of 30ohms? [Note: and additional series resistor ( variable) is also needed so the meter can be zeroed. the sero should be checked frequently by touching the leads together, sinc e the battery voltage can vary. Because of battery voltage variation, such ohmmeters are not precision instruments, but they are useful to obtain approx. values.]
