An electronic component with a 17-Ω resistor is rated for use at power levels not exceeding 14$ {~W}$ How much current can safely flow through the component?
A) 0.91 A
B) 1.21 A
C) 238 A
D) 0.22 A

The correct answer is A because the current through the resistor can be calculated using Ohm's law: I = V/R. Since the power is given by P = I^2 * R, we can solve for the current: I = sqrt(P/R) = sqrt(14 W / 17 Ω) = 0.91 A.
