Final answer:
Thomas Edison initiated a smear campaign against AC power and tried to undermine George Westinghouse by publicly associating AC power with the electric chair.
Step-by-step explanation:
Thomas Edison, an inventor known for his contributions to the electrical industry, was in competition with George Westinghouse, who developed and promoted alternating current (AC) power, while Edison favored direct current (DC) power. In an effort to undermine Westinghouse and the use of AC power, Edison initiated a smear campaign by publicly proclaiming AC power to be best adapted for use in the electric chair, hoping to create fear and reluctance in homeowners using AC power in their houses. As a result, the electric chair was created using AC power.
