Answer 1

To calculate the current flowing through the transmission line insulator, use Ohm's Law by dividing the voltage by the resistance.

Step-by-step explanation:

To calculate the current flowing through the transmission line insulator, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the resistance of each insulator is given as 1.00×10⁹Ω. The voltage of the transmission line is given as 200 kV.

To calculate the current, we can rearrange Ohm's Law to solve for I: I = V / R. Substituting the known values, we get I = 200,000 V / 1.00×10⁹ Ω = 0.2 mA.

Therefore, the current flowing through the insulator is 0.2 mA.
