Question
Why should an ammeter have a low resistance?
✓

Answer

An ammeter is connected in series with the circuit to read the current. If it had large resistance, it will change the current in circuit which it has to measure correctly; hence ammeter reading will have significant error; so for correct reading an ammeter should have a very low resistance.

Four $2\ cm \times 2\ cm \times 2\ cm$ cubes of ice are taken out from a refrigerator and are put in $200\ ml$ of a drink at $10^\circ C.$
  1. Find the temperature of the drink when thermal equilibrium is attained in it.
  2. If the ice cubes do not melt completely, find the amount melted. Assume that no heat is lost to the outside of the drink and that the container has negligible heat capacity. Density of ice $= 900\ kg-m^{-3}$, density of the drink $= 1000\ kg-m^{-3}$, specific heat capacity of the drink $= 4200Jkg^{-1}-K^{-1}$, latent heat of fusion of ice $= 3.4 \times 10^5J-kg^{-1}.$
