Explain why two devices can transfer the same amount of energy but have different powers if one transfers it faster.

Power is defined as the rate at which energy is transferred or work is done. When two devices transfer the same amount of energy, their power ratings can differ if one device completes the transfer more quickly than the other. For example, a light bulb that uses 60 joules of energy in 1 second has a power of 60 watts, while another device using the same energy in 2 seconds has a power of 30 watts. Thus, even though both devices transfer the same energy, the one that operates faster has a higher power rating, illustrating the relationship between energy transfer rate and power.
