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

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
