<h2>Answer:</h2>
is 3 ohms
In a circuit containing two resistors and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em><em> subject of the formula;</em>
=>
=>
=> ---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=>
= 3Ω
Therefore, the value of = 3 ohms or
= 3Ω
Divide by 21 to put the equation in intercept form.
x/(21/9) + y/(-21/7) = 1
x/(7/3) + y/(-3) = 1
The x-intercept is (7/3, 0)
The y-intercept is (0, -3)
The 3rd choice is appropriate.
