Solve.
-If the resistance in an electrical circuit is held constant, the amount of current flowing through the circuit varies directly with the amount of voltage applied to the circuit. When 2 volts are applied to a circuit, 40 milliamperes
Of current flow through the circuit. Find the new current if the voltage is increased to 15 volts.
A) 300 milliamperes
B) 320 milliamperes
C) 30 milliamperes
D) 285 milliamperes

Question

Quizplus · Accepted Answer

Using Ohm's Law (V = IR), if 2 volts produce 40 milliamperes, then 1 volt produces 20 milliamperes. For 15 volts, the current is 15 * 20 = 300 milliamperes.
