Question

four resistance of 12ohm each are connected in parallel. find such combinations in series. find the resultance of the combination​

Answer 1

Answer:

12 ohms

Explanation:

Given :

• Four resistors of 12 ohms are connected in parallel combination

• Such four combinations of four 12 ohm resistors are connected in series

To find :

• Resistance of such combination

Parallel combination effective resistance :

1/equivalent resistance = 1/12 + 1/12 + 1/12 + 1/12

1/equivalent resistance = 4/12

Equivalent resistance = 12/4

Equivalent resistance = 3 ohms

Such four 3 ohms resistors are connected in series

Equivalent resistance :

Equivalent resistance = 3+3+3+3

Equivalent resistance = 12 ohms

The resistance prevalent in the circuit is equal to 12 ohms
