The equation W=VIt defines the relationship between work (W), voltage (V), current (I), and time (t) in electrical circuits. It establishes that the work done is equal to the product of voltage, current, and the time during which the current flows. A common misconception is equating current with time; however, current represents the flow rate of charge, not a duration. Understanding this equation is crucial for analyzing power in electrical circuits.
PREREQUISITESStudents studying electrical engineering, educators teaching physics concepts, and anyone interested in understanding the principles of energy in electrical circuits.
1 A is a current and it does not take "time for it to flow". It is charge that flows. The current is the rate at which the charge flows.Daniel2244 said:My rough guess is : work done is equal to the time (t) taken for 1A of current to flow at 1V
If you do not understand the equation, but you know it must be applied to a circuit; maybe you should investigate equations and laws relative to electricity and circuitry.Daniel2244 said:Homework Statement
