Physics deflection ammeter
posted by andrew .
8. A galvanometer has a coil resistance of 100 ohms and gives a full scale deflection when the potential difference across it is 0.0002 V. What size resistor (with a value measured in ohms) is required to make a 1.0 A. full scale deflection ammeter?

current for meter: .0002/100=2E5 amps
so the shunt should carry .(12E5) amps
and the resistance =.0002/(12E5) ohms
2E3/(.99999) ohms 
thank you bob!

Plz tell me answer of this question...
