The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 5 amperes when the resistance is 888 ohms. What is the current when the resistance is 550 ohms? Round to the
Nearest tenth.
A) 8.1 amperes
B) 0.3 amperes
C) 3.1 amperes
D) 0.1 amperes

The relationship between current (I) and resistance (R) is given by I = k/R, where k is a constant. For I = 5 amperes and R = 888 ohms, we find k = 5 * 888. To find the current when R = 550 ohms, we use the same k and solve for I, resulting in I = k / 550, which gives approximately 8.1 amperes.
