Question

in the given circuit,given R1=10ohm, R2=6ohm and E=10V. Then which of the following statement are correct?​

Answer 1

Given:

R₁=10 ohm

R₂=6 ohm

E=10 V

Calculation:

As the value of resistance is same in both the branches, the current will not pass through the resistance R₁

Effective resistance of the circuit is given by

   $R_{eff}=\frac{4R_{1}\times 4R_{1}}{4R_{1}+ 4R_{1}}$

   $R_{eff}=\frac{40\times40}{40+40}$

   $R_{eff}=20\ ohm$

Effective resistance of the circuit is 20 ohm

Current passing through ammeter A₁ will be

    $I_{1}=\frac{E}{R_{eff}}$

    $I_{1}=\frac{10}{20}=\frac{1}{2}$

Current passing through ammeter A₁ is 1/2 A

Current passing through ammeter A₂ will be

    $I_{1}=\frac{E}{4R_1}$

    $I_{1}=\frac{10}{40}=\frac{1}{4}$

Current passing through ammeter A₂ is 1/4 A
