Q. Calculate the voltage drop across each resistance in given circuit.

 Solution:

In the circuit three resistors are in series and we desire to calculate the voltage drop across each of resistor this will be calculated as

                              The value of voltage drop across 50 k resistor

                          Through formula   V = R/R_t x V_t     

                                                    = 50k/100k x200 = 100V

                                         Now the voltage drop across 30k resistor will be

                                                V = 30/100 x 200

                                                   = 60 V

                                          Now the voltage across 20k resistor will be

                                                            V = 20/100 x 200= = 40 volts Ans
