Question

calculate the reading in ammeter B and C and also the total resistance
pl help ​

Answer 1

Answer:

B=0.5A

V=IR

I=V/R

if r1 and r2 are equal

then current through ammeter B and C will be same .

i.e= 0.5A

and therefore current in ammeter A will be 0.5+0.5 = 1 A

Answer 2

Explanation:

Given ammeter B reads 0.5 A current ✓

So,The full circuit will carry the same current

$\frac{v}{i} = r$

Given r = 2ohm and I= 0.5 A

So ,V = I×R

=> V= 0.5×2

=> 1 Volt ✓

To find the reading of other Ammeter u should to mention the reistances of other resistors ✓
