Hi there..
is anybody here know how to design one multi range voltmeter/ammeter by using a D’Arsonval meter with a full-scale deflection rating of 1mA and the internal coil resistance of 500Ω?
The measurement range of the voltmeter should cover the ranges as shown below.
Voltmeter Ammeter
1) 0-1V 0-10mA
2) 0-5V 0-50mA
3) 0-10V 0-100mA
4) 0-20V 0-1A
5) 0-50V 0-10A
6) 0-100V 0-20A
7) 0-200V 0-50A
8) 0-300V 0-60A
9) 0-400V 0-80A
10) 0-500V 0-100A
Can u tell me the step hw to do n any ref of this...
thx 4 helping... i really appreciate it...

It's all about ohms law. Nothing more. This sounds like homework BTW.
