Which outcome occurs when lightning strikes near transmission lines?

💡 Explanation

Lightning causes a rapid change in electromagnetic field. Because electromagnetic induction generates voltage pulses in the transmission lines, the increased voltage can damage equipment; therefore significant power surges transpire, rather than dielectric breakdown from constant voltage.
