Electricity - Series and Parallel Circuits पर अभ्यास प्रश्न — उत्तर सहित

Try each question first, then open the answer. Explanations are included.

1. Two resistors of 10 ohm and 5 ohm are connected in series. What is the total (equivalent) resistance?

  1. A14
  2. B10
  3. C25
  4. D15
उत्तर दिखाएँ

उत्तर: D

In series, resistances add directly: R = R1 + R2 = 10 + 5 = 15 ohm.

2. Two resistors of 12 ohm and 12 ohm are connected in parallel. What is the total (equivalent) resistance?

  1. A6
  2. B16
  3. C6.934
  4. D7
उत्तर दिखाएँ

उत्तर: A

In parallel: R = (R1 x R2)/(R1 + R2) = (12 x 12)/(12+12) = 144/24 = 6 ohm.

3. Two resistors of 14 ohm and 6 ohm are connected in series. What is the total (equivalent) resistance?

  1. A10
  2. B15
  3. C20
  4. D30
उत्तर दिखाएँ

उत्तर: C

In series, resistances add directly: R = R1 + R2 = 14 + 6 = 20 ohm.

4. Two resistors of 10 ohm and 15 ohm are connected in series. What is the total (equivalent) resistance?

  1. A30
  2. B35
  3. C23
  4. D25
उत्तर दिखाएँ

उत्तर: D

In series, resistances add directly: R = R1 + R2 = 10 + 15 = 25 ohm.

5. Two resistors of 16 ohm and 28 ohm are connected in series. What is the total (equivalent) resistance?

  1. A54
  2. B36.005
  3. C44
  4. D49
उत्तर दिखाएँ

उत्तर: C

In series, resistances add directly: R = R1 + R2 = 16 + 28 = 44 ohm.
