A)0.2 ohms
B)29.8 ohms
C)14.8
D)5.2 ohms

Question

Quizplus · Accepted Answer

Using the formula given, 
Resistance (in ohms) = Voltage (in volts) ÷ Current (in amperes)
Substituting the given values, 
Resistance (in ohms) = 12.4 V ÷ 2.4 A
Resistance (in ohms) = 5.1666667 ohms (rounded to 1 decimal place)
Therefore, the closest answer choice is D, which is 5.2 ohms (rounded to 1 decimal place).
