Final answer:
You can power 6-10 grandfather clocks with the same amount of power as a single light bulb.
Step-by-step explanation:
To figure out how many grandfather clocks you can power with the same amount of power as a single light bulb, we need to compare the power ratings of the two devices. A typical light bulb uses around 60-100 watts of power, while a grandfather clock requires very little power as it is mainly mechanical and relies on the potential energy stored in the weights and pendulum. Assuming a grandfather clock uses 10 watts of power, you can power 6-10 grandfather clocks with the same amount of power as a single light bulb.
