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=2E-5 amps
so the shunt should carry .(1-2E-5) amps
and the resistance =.0002/(1-2E-5) ohms
thank you bob!
Plz tell me answer of this question...
