Question

Reading of ammeter A1 and A2 is respectively

Answer 1

Ammeter A1 and A2 is respectively

Explanation:

• The bulb are identical so that R1 = R2 = R3 =R
• Thus, R' R/3
• According to the ohm's law  V = IR
• If voltage is given 4.5 V and current pass is 3 A resistance.
• Now we substitute it as 4.5 = 3*(R/3)
• Hence the resistance power is R1 = R2 = R3 = R = 4.5 ohm's
• If we consider the two bulb work and third one get fused then it will be 2 A
• Thus here ammeter A1 shows 1, A2 = 0 B2 blow off. A2 shows 2 ampere.
