Use the information provided to write a formula for the given inverse variation
The amount of current I flowing through a circuit is inversely proportional to the amount of resistance R of the circuit. In a circuit with a resistance of 18 ohms, the current is 0.25 amperes

The constant that the others reference is Voltage (or V)
V = I * R
V = 18 * .25 = 4.5 volts.

Current (I) inversely proportional to Resistance (R):
I = K/R (K = constant)
K = 4.5 volts
Here, K is 'Volts'

constant = lR = 0.25(18) = 4.5
R l = 4.5 or R = 4.5 / l or l = 4.5 / R

I = k/R
.25 = k/18
k = 18*.25 = 4.5
I = 4.5/R <-----answer
