What is the equivalent resistance for a parallel circuit that has two resistors: 18.0 ohms and 23.5 ohms?
2 answers:
Answer: A. 10.2 ohms
On Plato
Explanation:
... take the reciprocal of each resistor.
... add the fractions
... take the reciprocal of their sum; that's the answer.
When there are only two resistors, here's an easier way:
... find their product
... find their sum
... divide the product by the sum; that's the answer.
Your parallel resistors make 10.193 ohms.
