What is the resistance in a circuit that carries a 0.75 a current when powered by a 1.5 v battery? a.) 0.50 ω b.) 1.1 ω c.) 2.0 ω d.) 2.3 ω

It is 2.0 Ω because R=V/I so 1.5V/.75A = 2Ω

Option (C) is the correct answer.

Explanation:

According to ohm's law, current flowing through a circuit is directly proportional to the voltage over resistance.

Mathematically,        

where,         I = current

                   V = voltage

                   R = resistance

Therefore, it is given that current is 0.75 A and voltage is 1.5 V. Thus, calculate the resistance as follows.

or,                    

                                    =

                                    =

                                    = 2 ohms

Hence, we can conclude that resistance in the circuit is 2 ohms.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.
