Which of the following statements are true statements about lightning rods? Choose all that apply. Lightning rods are placed on homes to reduce the risk of lightning damage to a home. Any metallic object which is placed on the roof of a home and grounded by an appropriate conducting pathway can serve as a lightning rod. Most lightning rods are pointed as a decorative feature. To be totally effective, a lightning rod must stretch high into the sky and draw charge from the lowest clouds by the method of contact. Lightning rods are capable of reducing the excess charge buildup in clouds, a characteristic of dangerous thunderstorms. Charge is incapable of passing from clouds to a lightning rods since the air between the clouds and the lightning rod has an insulating effect. The electric field strength about the points of lightning rods are very high.
