Question

plz answer me fast plz plz ​

Answer 1

hi mate

as you know

1/R = x * 1 /150

R = 150/x

from ohm's law

V/I =150/x

x = 150 * I / V

x = 150 * 5 / 250

x =750/250

x = 3

Answer 2

Answer: 9 resistor

Explanation:  Given: V =250volt ; I = 15A

         Equivalent resistance     R=  v       = 250V       =    50 ohm

                                                         I             15A               3

 let n e the no of resistor each of 150 ohm  are connected in parallel.

so , their equivalent resistance become 50/3 ohm then

            3      =     1     +      1    +      1    + ...............+n times

           50         150         150       150

         

             3   =     n    

            50        150

         

              n =  3 * 150

                         50

                 

               n= 9
