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:
V = IR
Total current = V/R = 12/13 amp = 0.92 A
since ,
I(battery) = I1 = I2 = I3 = 0.92 A
Ans:- ( D )
