A tangent galvanometer of resistance `10Omega` shows a deflection of `60^(@)` when inserted in a circuit whose total resistance (including that of the galvanometer) is `100Omega`. What shunt must be used to reduce the deflection to `30^(@)`?

A galvanometer coil of resistance 50 Omega , show full deflection of 100 muA . The shunt resistance to be added to the galvanometer, to work as an ammeter of range 10 mA is

A galvanometer of resistance 10Omega shows full scale deflection for current 100 mA. The resistance that needs to be connected in series with the galvanometer so that it can be used to measure potential difference in the range 0-100 V is (in Ohm):

The deflection in a M.C.G. is reduced to half , when it is shunted with a 40 Omega coil. The resistance of the galvanometer is

The deflection in a galvanometer decreases to 1/5th of the original deflectioon, if it is shunted by a resistance of 5 Omega. The resistance of the galvanometer is
