Which of the following symbols represents $\mathrm{power}$?

• A. $W$
• B. $P$
• C. $E$
• D. $F$

Answer: (B)

Verified step by step guidance

1. Understand that in physics, power is defined as the rate at which work is done or energy is transferred over time.
2. Recall the common symbols used in physics: \( W \) typically represents work or energy, \( E \) represents energy, \( F \) represents force, and \( P \) represents power.
3. Recognize that power is mathematically expressed as \( P = \frac{W}{t} \), where \( W \) is work done and \( t \) is the time taken.
4. Since power is the rate of doing work, the symbol \( P \) is conventionally used to denote power in physics equations and problems.
5. Therefore, among the given options, \( P \) correctly represents power.
