Find the unknown resistance in the figure shown, to the nearest hundredth of an ohm, if the total (equivalent) resistance is 0.28

Please help asap!

The unknown resistance is approximately 0.44 Ω.

Solution:

Total (equivalent) resistance = 0.28 Ω

Resistance 1 = ?

Resistance 2 = 0.81 Ω

To find the unknown resistance.

Formula for determining equivalent resistance in a parallel circuit:

Substitute the given values in the formula.

Subtract 1.235 on both sides of the equation, we get

Take reciprocal to find .

= 0.44 Ω

The unknown resistance is approximately 0.44 Ω.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
