rm R 5. (6 points) Consider the circuit above, where V = 10.0 V and R = 140.0 . R indicates the resistor i this circuit and rm is the resistance of a voltmeter which is used to measure the circuit. The voltmeter i connected in parallel with resistor R to make the measurement, as shown. What should be the resistance of the voltmeter r,,, so that 99% of the current goes through resistor R? Based on your answer, would you say that voltmeters should have high resistance or low resistance?
