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. The ammeter should have a range sufficient for measuring a given current. The design of digital "movements" is beyond the scope of this chapter, but mechanical meter movement designs are very understandable. This way, there will be no deflection in ampere meter due to no current flowing through ammeter and load. CBSE Class 10 Science Important MCQs: All Chapters. CBSE Class 10 Science Syllabus 2017-2018. unit of current is ampere. DC Ammeter are mainly PMMC instruments, MI can measure both AC and DC currents, also Electrodynamometer type thermal instrument can measure DC and AC, induction meters are not generally used for ammeter construction due to their higher cost, inaccuracy in measurement.. (a) Draw a circuit diagram of the connection. This is done by adding a high resistance in series with the ammeter. INTO AMMETER. The ideal resistance of an ammeter should be zero. This is how you determine direction of current using a meter. Check important topics and marking scheme as per the new exam pattern by the board. Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter.
