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

6.67 ohms

Explanation:

Answer 2

6 2/3

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.
