Two resistors 10 ohm each can be connected to give a combined resistance of?
Answers
Answer:
Series = 20 ohms
Parallel = 5 ohms
Explanation:
Series combination:
When two resistors are connected in series, Req = R1 + R2
Here R1 = 10 ohms
R2 = 10 ohms
So Req when connected in series = 10+10
Req = 20 ohms
Parallel combination:
When two resistors are connected in parallel, 1/Req = 1/R1 + 1/R2
1/Req = 1/10+1/10
1/Req = 2/10
Req = 10/2
Req = 5 ohms
The two 10 ohms resistors can be connected in series to provide equivalent resistance of 20 ohms and in parallel to provide equivalent resistance of 5 ohms
