Web11 okt. 2016 · Your approach seems right - i.e. that a voltmeter measurement of the voltage across a know resistor can be used as an ammeter, which will then allow you to measure the resistance of an in-series resistor through a voltage measurement across the latter. You also rightly point out that the voltmeter draws some current, and thus introduces a … WebResistors are needed to set currents and adjust voltage levels through a series circuit. They are used for other functions too, like part of frequency filters, oscillators etc. etc. 7.Why do different light bulbs work on the same battery (different resistance, but no dead short?) Different light bulbs have different resistances.
