Solve the problem.
-If the voltage, V, in an electric circuit is held constant, the current, I, is inversely proportional to the resistance, R. If the current is 280 milliamperes when the resistance is 5 ohms, find the current when the resistance is 35 ohms.
A) 200 milliamperes
B) 40 milliamperes
C) 1953 milliamperes
D) 1960 milliamperes

The relationship between current (I), voltage (V), and resistance (R) is given by Ohm's law, V = IR. If the current is inversely proportional to the resistance while the voltage is constant, then I1R1 = I2R2. Given I1 = 280 milliamperes and R1 = 5 ohms, for R2 = 35 ohms, I2 = (I1R1)/R2 = (280*5)/35 = 40 milliamperes.
