10:35 Thu 8 Aug Cancel Markup a) b) A milliammeter shows full-scale deflection for a current of 5 mA. It has a low resistance of 5 2 which for the purpose of this question you may take as zero. Explain with a suitable diagram how it may be adapted for use as a voltmeter for any desired voltage range, e.g. 0-200V. Calculate the resistance of the voltmeter if this is the chosen range. A millivoltmeter shows full-scale deflection for a voltage of 10 mV. It has a resistance of 50k which for the purpose of this question you may take as infinite. Explain with a suitable diagram how it may be adapted for use as an ammeter for any desired current range, e.g. 0-10A. Calculate the resistance of the ammeter if this is the chosen range. 5 C זיייייייייייי 50 + 16% 14 Done
