What does the symbol P stand for in energy contexts?

Power describes how quickly energy is transferred or used. In energy contexts, the symbol P is used to denote this rate. If a device has power P, it transfers energy at P joules per second, so the total energy transferred over time t is E = P × t. For example, a 60 W light bulb transfers 60 J of energy every second, so in 60 seconds it would transfer 3600 J. Other symbols apply to different ideas: pressure is typically labeled with P in different contexts but uses different units (pascals), potential energy is often shown as U or PE, and position is usually represented by x or s.
