The current l, in a circuit varies inversely with the resistance, R. If the resistance is 12 when the current is 3, what is the
ivolga24 [154]

Answer:

6

Step-by-step explanation:

Given I varies inversely with R then the equation relating them is

I =  \frac{k}{R} ← k is the constant of variation

To find k use the condition R = 12 when I = 3

k = IR = 3 × 12 = 36

I = \frac{36}{R} ← equation of variation

When I = 6, then

6 = \frac{36}{R}, hence

R = \frac{36}{6} = 6

Where does the point (0, - 3) lie?
White raven [17]

This point falls on none of your possible answers.

We can first tell that it falls neither positive or negative in terms of x since the x value is 0.

We can also tell the y term is negative. Therefore, it would fall on the negative y-axis.
