Question Discussion & Solution

The correct answer is Ammeter.

Key Points

• Ammeter
  • An ammeter is an instrument that is used to measure the current in the circuit.
  • It measures either direct or alternating electric current, in amperes (A).
  • It has a set of coils with very low resistance and inductive reactance.
  • This allows for very low impedance, the force that opposes electric current.

Additional Information

• Wattmeter
  • The wattmeter is an instrument for measuring the electric active power in watts of any given circuit.
  • Electromagnetic wattmeters are used for the measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.
• Hygrometer
  • Hygrometer instrument used in meteorological science to measure the humidity or amount of water vapour in the air.
• Pyrometer
  • A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects

Given: Ship : Sea :: Camel : ?

Logic:

Ship sails on the Sea.

Similarly,

Camel walks in the Desert.

Hence, Desert is the correct answer.

Given series: 2, 5, 10, 17, 26, 37, 50, 65, 82, _________

The logic is:

2 + 3 = 5

5 + 5 = 10

10 + 7 = 17

17 + 9 = 26

26 + 11 = 37

37 + 13 = 50

50 + 15 = 65

65 + 17 = 82

82 + 19 = 101

Explanation:

• The metallic property of the elements of the periodic table decreases when we move across the group whereas it increases when we go down the group, as we go down the number of electrons increases and thereby their distance from the nucleus increases. 
• This increase causes them to shed more electrons and thereby have a greater electropositive or metallic character. 

Among the given compounds Na shows maximum Metallic character.
