Answer 2

Formulas regarding the questions are given below.

Explanation:

1. For a circuit, the total resistance can be calculated by calculating effective resistance.

        So, for resistors in parallel, add their reciprocals to find the reciprocal of effective resistance.        

                                                ⇒ $\frac{1}{R} = \frac{1}{R_{1} } + \frac{1}{R_{2} }$      

       And, for resistors in series, add them as usual to get effective resistance.

                                              ⇒  R = $R_{1}$ + $R_{2}$                                  

     2. The current through the circuit can be known by the formula,

                                       ⇒ I = $\frac{V}{R}$

     3. The potential difference across RI and R2 is

                                          ⇒ V =IR
