According to ohms law if you don't change the value of the resistor and you double the voltage in a circuit the amount of current flowing will a. be multiplied by the amount of resistance b. remain the same also c. divide it in half d. double

D (doubled)

According to ohm's law

                      I = V/R ,

                      V = IR ;   R = constant and V is doubled

  From the equation

                      V is directly proportional to the current, and it is given that R is constant ;

                    2V = 2I. R    since R = constant

                      Hence I is doubled.

d) physical means can be used to separate the components of air.
