A scientist set up an experiment to collect data
about lightning. In one lightning flash, a charge of
25 coulombs was transferred from the base of a
cloud to the ground. The scientist measured a
potential difference of 1.8 x 106 volts between the
cloud and the ground and an average current of
2.0 × 104 amperes.
The scientist was several kilometers from the
lightning flash. Using one or more complete
sentences, explain why the scientist saw the
lightning flash several seconds before he heard the
