Technician A says that Ohm's law can be used to determine circuit current flow if total circuit resistance and total voltage are known. Technician B says that Ohm's law can be used to calculate the unknown resistance of a load in a circuit if total current and source voltage are known. Which technician is correct?

Question

Quizplus · Accepted Answer

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. This means that if you know any two of the three variables (voltage, current, resistance), you can calculate the third. Therefore, both Technician A and Technician B are correct in their statements.
