Displacement Current

Step 1: Use the formula for charge The total charge passing through a conductor is given by the formula: where: - is the current (2 A), - is the time the current flows (in seconds). Step 2: Convert time into seconds Given: - Current , - Time . Step 3: Substitute the values into the formula Answer: Therefore, the total charge that flows through the resistor is 240 C. So, the correct answer is option (3).

Step 1: Use Ohm's law Ohm's law states that the relationship between voltage ( ), current ( ), and resistance ( ) is: Step 2: Rearrange to find the resistance Rearranging the formula to solve for resistance : Step 3: Substitute the given values Given: - , - . Substitute these values into the formula: Answer: Therefore, the resistance of the conductor is . So, the correct answer is option (1).
