Question 1200307
the inverse proportion formula is y = k / x
k is the constant of variation.
when you keep V constant, then V becomes the constant of variation and you get:
k becomes V
y becomes I
x becomes R
the inverse proportion formula becomes I = V / R
if the current is 60 amperes when the resistance is 228 ohms, the formula becomes:
60 = V / 228
solve for V to get V = 60 * 228 = 13680.
that becomes the constant of variation because it doesn't change.
when the resistance is 120 ohms, the formula of I = V / R becomes:
I = 13680 / 120
solve for I to get I = 114 amperes.
that should be your answer.
