which question to answers

Answer 2

Answer:

Reff = 4Ω Total current I = A

Explanation:

i) R1 and R2 are in parallel

effective resistance of parallel combination is

Rp = R/2 = 2/2 = 1 Ω

Rp is in series with 3 Ω

∴ Total effective resistance Reff= Rp + 3 = 1+3= 4Ω

ii) Total current I = V/Reff= 4/4= 1A

iii) p.d across R3 is V3 = I R3 = 1 x 3 = 3 V

p.d across R1 and R2 is same = V-V3 = 4 - 3 = 1 V
