The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for R2, in terms of RT and R1, what is R2 R2 blank is ohms

 is 3 ohms

In a circuit containing two resistors and connected together in parallel, the total resistance is given by;

             ---------(i)

Make subject of the formula;

=>  

=>

=>         ---------------(ii)

From the question,

= 6Ω

= 2Ω

Substitute these values into equation (ii) as follows;

=>

= 3Ω

Therefore, the value of = 3 ohms or = 3Ω

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
