Question

Two resistances are in the ratio 1 : 4. If these are connected in parallel, their total resistance becomes 20 ohm . Calculate the value of
each resistance.
[PSEB 2000]​

Answer 1

Answer:

the answer is 4 .

Explanation:

1x+4x= 5

20/5=4.

Answer 2

Answer:

$r = \frac{20}{1 + 4}$

$r = \frac{20}{5}$

RESISTANCE = 4

1 ST VALUE = 4 × 1 = 4

2 ND VALUE = 4 × 4 = 16
