The ammeter must also be invisible (drop no voltage). […] }[/math] Stated simply, the voltmeter must be invisible (draw no current). Analog meters still have some applications, however, for the beginner or even the experienced electrician, I would recommend a digital meter and that is why you will not find any analog meters for sale here. CBSE Class 10 NCERT Textbooks & NCERT Solutions. A 0.0200-Ω ammeter is placed in series with a 10.00-Ω resistor in a circuit. If we move the switch to the ON position, the flow of electron (current) will be moving this way as shown in below fig. ammeter. Requirements of Good Ammeter: The resistance of an ammeter must be as small as possible. This way, there will be no deflection in ampere meter due to no current flowing through ammeter and load. Select a range you wish to check. Class 10 Science Chapter 12 Board Questions for exams practice are given below. Current in ammeter, A = 2 ampere. Answers of all board papers questions are given just below the questions.
