Q1. Study the diagram 8.47 carefully and calculate :

       (a) the equivalent resistance between P and Q.

                    

       (b) the reading shown by ammeter,

       (c) the electrical power between P and Q.
 

Dear Student,

            (i).  As we can see from figure given in the question, the two resistors of resistances 3 ohm and 6 ohm are connected in parallel. Let there equivalent resistance be R.
                         1R=13+16 1R=2+16 R = 2 ohm.
           (ii). The reading of ammeter or current in the circuit, I = V/R
                                                                                                   = 2/2
                                                                                                   =1 A.

            (iii). Power between P and Q, 
                                                                   P = VI
                                                                      = 2 x 1
                                                                      = 2 W.
