Question 78Electricity & Electronics - QMED

The correct answer is C) be divided by two. In a simple DC circuit, the current is directly proportional to the applied voltage and inversely proportional to the resistance, as described by Ohm's law: I = V/R. If the resistance is held constant while the applied voltage is halved, the current will also be halved, since I is directly proportional to V. Therefore, the current flow will be divided by two compared to the original current. The other options are incorrect because: A) doubling the current would violate Ohm's law, B) the current cannot remain the same if the voltage is reduced, and D) dividing the current by four would require the voltage to be reduced by a factor of four, not two.
