Question

Q2.Find the reading of ammeters A1 and A2?
​

Answer 1

Answer:

A1shows amphere and A2 shows zero as bulb

Answer 2

Answer:

current through $A_{1}$ = 20 amp.

current through $A_{2}$ = 20/3 amp.

Explanation:

Let the current through $A_{1}$ be $I_{1}$ and current through $A_{2}$ be $I_{2}$.

And the effective ressistance can be found using series and parallel combinations as $R_{eff}$ = 10 Ω.

Applying ohm's law(V=IR),

   200 = $I_{1}$*10

=> $I_{1}$ = 20 amperes.

And 200 = $I_{2}$*30

  =>  $I_{2}$ = 20/3 amperes.
