Explanation

Solution: This question relates to Ohm's Law , a fundamental principle in electricity. Ohm's Law states: V = IR , where: V is the potential difference (voltage). I is the current . R is the resistance . The question says that the potential difference (V) is doubled . Let's say the initial potential difference was V1 and the initial current was I1. So, V1 = I1 * R. Now the potential difference becomes V2 = 2 * V1. Since the resistance (R) of the conductor remains constant , we can rewrite Ohm's Law for the new situation as: 2 * V1 = I2 * R, where I2 is the new current. To find the relationship between I1 and I2, we can substitute V1 = I1 * R into the equation 2 * V1 = I2 * R: 2 * (I1 * R) = I2 * R Divide both sides by R: 2 * I1 = I2 This means the new current (I2) is twice the original current (I1) . Therefore, the correct answer is: A: will be doubled
