SATHEE: Current Electricity 4 Question 19

Current Electricity 4 Question 19

19. A moving coil galvanometer of resistance $100 Ω$ is used as an ammeter using a resistance $0.1 Ω$ . The maximum deflection current in the galvanometer is $100 μ A$ . Find the current in the circuit, so that the ammeter shows maximum deflection.

(2005, 2M)

(a) $100.1 m A$

(b) $1000.1 m A$

(c) $10.01 m A$

(d) $1.01 m A$

Show Answer

Solution:

$V_{a b} = i_{g} \cdot G = (i - i_{g}) S$

$\Rightarrow i = 1 + \frac{G}{S} i_{g}$

Substituting the values, we get

$i = 100.1 m A$

$∴$ Correct answer is (a).
