सही विकल्प 4 है। 

अवधारणा:  

  • चूँकि दी गई इनपुट सीमा 10 V है और हमें 60 V DC का मापन करना है।तो उपयुक्त न्यूनतम स्केल प्रोब  10 X होगा।
  • क्योंकि यह  100 V तक की श्रेणी का मापन प्रदान करता है।
  • हम यहाँ 1 X स्केल प्रोब का उपयोग नहीं कर सकते हैं क्योंकि यह केवल 10 V तक की श्रेणी का मापन प्रदान करता है।
  • जबकि हम 250 V DC के मापन के लिए 100 X & 1000 X स्केल प्रोब का उपयोग कर सकते हैं क्योंकि यह क्रमशः 1000 V और 10000 V तक की श्रेणी का मापन प्रदान करता है।
