Question

How the three conductors of resistances 2, 3 and 6 ohm, should be connected to a cell so as the value of current flowing may be maximum ? Also draw the circuit diagram of the arrangement. Calculate the equivalent resistance of the circuit the internal resistance of the cell is negligible.​

Answer 1

• Fertilizers play an important role for soil health: they supplement the natural supply of soil nutrients, build up soil fertility in order to satisfy the demand of crops with a high yield potential and compensate for the nutrients taken by harvested products or lost by unavoidable leakages to the environment, in order ...

Let the age of father be x years

Let the age of one of his children be y years and age of other children be z years

From given information,

x=2×(y+z)...(1)

After 20 years,

(x+20)=(y+20)+(z+20)...(2)

Substituting value of (1) in (2), we get

2×(y+z) +20=y+z+40

2y+2z−y−z=40−20

y+z=20...(3)

Substituting value of (3) in (1), we get

x=2×(20)

⇒x=40
