Answer 2

Calculating Current in the Conductor

When the voltage across a conductor is 8 V and the current through it is 0.32 A, we can use Ohm's law to calculate the resistance of the conductor and then use it to find the current when the voltage is increased to 17 V.

Step 1: Calculate the Resistance of the Conductor According to Ohm's law, the resistance (R) can be calculated using the formula: R = V / I Where: - R = resistance - V = voltage - I = current

Using the given values: V = 8 V I = 0.32 A

We can calculate the resistance: R = 8 V / 0.32 A R = 25 Ω

Step 2: Calculate the Current when Voltage is 17 V Now, we can use the resistance we calculated to find the current when the voltage is increased to 17 V. Again, using Ohm's law: I = V / R Where: - I = current - V = voltage - R = resistance

Using the new voltage value: V = 17 V R = 25 Ω

We can calculate the current: I = 17 V / 25 Ω I ≈ 0.68 A

Therefore, the current in the conductor, when the voltage across its ends is increased to 17 V, will be approximately 0.68 A.
