Answer 2

Calculation of Voltage in the Conductor

To calculate the voltage in the conductor, we can use Ohm's Law, which states that the voltage (V) is equal to the current (I) multiplied by the resistance (R). In this case, the resistance of the conductor is not given, but we can assume it to be constant.

Given: - Initial voltage (V1) = 16 V - Initial current (I1) = 0.4 A

Using Ohm's Law, we can write the equation as: V1 = I1 * R

To find the resistance (R), we can rearrange the equation as: R = V1 / I1

Now, we can calculate the resistance using the given values: R = 16 V / 0.4 A = 40 Ω

Calculation of Voltage with Increased Current

To find the new voltage (V2) when the current (I2) becomes 0.8 A, we can use the same equation: V2 = I2 * R

Substituting the values: V2 = 0.8 A * 40 Ω = 32 V

Therefore, when the current in the conductor becomes 0.8 A, the voltage in the same conductor will be 32 V.

Please note that the above calculations assume a constant resistance in the conductor.
