Question 443Electricity & Electronics - Assistant Engineer

The correct answer is C) be divided by two. In a simple DC circuit, the current flow is directly proportional to the applied voltage and inversely proportional to the resistance, as described by Ohm's law: I = V/R. When the applied voltage is halved while the resistance remains constant, the current flow will also be halved. This is because the current is directly proportional to the voltage, so if the voltage is reduced by half, the current will also be reduced by half. 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 changed, and D) dividing the current by four would imply that the resistance has also changed, which is not the case in this scenario.
