Which equation represents ohm’s law?

a. current = voltage × resistance

b. voltage = current × resistance

c. resistance = current × voltage

(B) Voltage = Current × Resistance

Explanation:

Ohm's law states that the voltage is directly proportional to the current flowing. Mathematically, it can be written as:

R is the constant of proportionality and it opposes the flow of electric current in the wire called as the resistance.

In terms of length and the area of cross section of the wire the resistance can also be written as :

is the specific resistance or resistivity

l and A are length and the area of cross section

So, the correct option is (B) " Voltage = Current × Resistance ".

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

  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.

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