QUESTION 2
(a)
A multirange ammeter needs to be designed with four measurement ranges:
PIS Come to wha
+6-172917209
Range 1: 0 – 1 mA
Range 2: 0 – 20 mA
Range 3: 0 – 50 mA
Range 4: 0 – 100 mA
foC
A D’Arsonval meter movement with an internal resistance of 500 SN and full scale
Ray
current of 100 µA is used.
i)
Design each resistor values for the multirange ammeter using the principle of
Aryton Shunt.
wak
ii)
If
you were to construct this ammeter, how would you arrange the resistors?
Sketch a schematic diagram to show
your design.
mongy
(b)
multirange DC voltmeter can be designed either with the multiplier resistors
connected in shunts or in series.
bwena
D'Arsonval meter movement with Im = 100 µA and Rm
1.4 kQ is to be
converted into a multirange DC voltmeter for ranges of 5 V, 10 V, 20 V and 50
V. Calculate the multiplier resistor values for both types of design.
ii)
Based on the calculation results, give your opinion on which design is better
and provide your reason.
