I think the answer is 28 miles
Answer:
The current flows through the insulator is 2 mA.
Explanation:
Given that,
Resistance 
Voltage = 200 kV
We need to calculate the current
Using ohm's law


Where, I = current
V = voltage
R = resistance
Put the value into the formula



Hence, The current flows through the insulator is 2 mA.
Experimental Evidence.
Scientists conduct experiments or observations to gather evidence that either support or disprove a given hypothesis. Hence, all the scientific explanations are based on this body of observations.
