Show that , if the range of an ammeter is increases n times, its resistance decreases n times.

Show that, if the range of an ammeter is increased n times, its resistance becomes (1)/(n) times its previous value.

Show that , if the range of a voltmeter is increases n times, its resistance also increases n times.

Range of an ammeter is increases by n times. What is the change in its resistance ?

If the current sensitivity of a moving coil galvanometer is increased by 20% , its resistance also increased by 1.5 times. How will the voltage sensitivity of the galvanometer by affected?

If the voume of a sphere is incereased by 8 times, then its radius will be increased by

Statement : I A galvanometer of resistance G is converted to an ammeter by increasing its range n times. The resistance of the ammeter is (G)/(n) . Statement : II A shunt of resistance (G)/(n-1) has to be connected in parallel with a galvanometer in order to increase its range n times.

What is the change in resistance of a Voltemter if its range is increases by n times ?

Show that if n identical conductors are joined in series, the combined resistance is n^2 times as great as when they are joined in parallel.
