alleryResistors of 2, 3 and 5 ohm are joined in series. What is the total resistance?
A10 ohm
B30 ohm
C3.3 ohm
D1 ohm
Answer & Solution
Correct answer: A. 10 ohm
1. Series resistances add.
2. 2 + 3 + 5 = 10 ohm; 30 comes from multiplying and the others from wrongly using reciprocals.
3. So the total is 10 ohm.
