<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
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
2nd one: 2 rectangles can have thr same area but have different perimeters.
