Answer 1

Answer:

OPTION B

2 AMPERE

Explanation:

★ ALL 3 BULBS IN CIRCUIT ARE IN PARALLEL COMBINATION .

★ SO ; Equivalent Resistance ( R ) =

1 / R = 1 / R1 + 1 / R2 + 1 / R3

1 / R = 1 / 4 + 1 / 3 + 1 / 6

★ R = 24 / 18 = 4 / 3 Ω .

______________________________________

★ In Parallel ; Potential Difference across each bulb is same .

So ; Current through 6 Ω bulb

I = V / R = 12 / 6 = 2 AMPERE .

Answer 2

Answer:

V = IR

Total current = V/R = 12/13 amp = 0.92 A

since ,

I(battery) = I1 = I2 = I3 = 0.92 A

Ans:- ( D )
