  Find out the following -in the electric circuit given in figure (a) effective resistance of two  resistors in the combination (b) current flowing through  resistor (c) potential difference across  resistance (d)power dissipated in  resistor (e) difference in ammeter readings, if any  

Answer:

                  (a) Since, two resistors are in parallel, then their effective resistance is given by (b) Total resistance in the circuit Current through the circuit' Thus, current through  resistor is 1 A as  and  are in series and same current flows through them. (c) Potential difference across resistor is potential drop by the  resistor i.e,         (d) Power dissipated in  resistor (e) There is no difference in the readings of ammeters  and  as same current flows through all elements in a series current.
