Inverse Variation

Question 9 • EAP-Algebra Functions and Data Analysis B

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 2 amperes when the resistance is 770 ohms. What is the current when the resistance is 808 ohms? Round your answer to two decimal places if necessary.

Answer
A
1.9 amps
B
2.1 amps
C
0.48 amps
D
0.52 amps

Explanation

Since current varies inversely with resistance, I × R is constant. The constant is 2 × 770 = 1540, so at 808 ohms the current is 1540 ÷ 808 ≈ 1.91 amps. This matches choice a, 1.9 amps.
