In Ohm's law, what does the symbol I represent?

• A. Voltage
• B. Current
• C. Resistance
• D. Power

Answer: (B)

In Ohm's law, the symbol I represents current. Ohm's law is a fundamental principle in electrical engineering and describes the relationship between voltage (V), current (I), and resistance (R) in a circuit. According to the law, the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. This relationship can be expressed with the formula I = V/R, where current is measured in amperes (A). Understanding that I stands for current is crucial for analyzing and designing electrical circuits, as it allows for the calculation of how much charge is flowing through a circuit per unit time.
