Mathematics · Electrical Measuring Instruments - Voltmeter Design
यदि PMMC उपकरण का उपयोग करने वाले एक DC वोल्टमीटर की संवेदनशीलता (sensitivity) 10 kΩ/V है और आंतरिक मीटर प्रतिरोध 500 Ω है, तो 10 V रेंज वाले वोल्टमीटर के लिए पूर्ण-पैमाना विक्षेपण धारा (full-scale deflection current) और आवश्यक गुणक श्रृंखला प्रतिरोध (multiplier series resistance) क्रमशः होंगे:
- 10.1 mA; 0.5 Ω
- 210 mA; 9.95 kΩ
- 30.1 mA; 99500 Ω✓
- 410 mA; 500 Ω
सही उत्तर देखें
0.1 mA; 99500 Ω
