Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Option 2, i.e 10 ohm.
- Given that two resistors of 20 ohms are connected in parallel.
- So, the resultant resistance
- 1/Rc = 1/R1 +1/R2 = 1/20 + 1/20 = 1/10 ohm
- So, Rc = 10 ohm
- A voltage source offers very minimal resistance. Hence, the total resistance is 10 ohms.
