Question

Voltage varies directly with current. A remote control uses a 3-volt battery and has an electric current of 0.45 amps. What is the constant of proportionality?

Answer 1

Answer:

  6 2/3

Step-by-step explanation:

Let the constant of proportionality be represented by "r". Then ...

  V = I·r . . . . . where V represents voltage and I represents current

  3 = 0.45r

  3/0.45 = r = 1/.15

  r = 6 2/3

The constant of proportionality is 6 2/3.
