According to Ohm's law, how is voltage represented?

Ohm's law is fundamental in understanding the relationship between voltage, current, and resistance in electrical circuits. The formula represented as V = iR clearly indicates that voltage (V) is equal to the current (i) flowing through a conductor multiplied by the resistance (R) of that conductor. This relationship emphasizes that for a constant resistance, an increase in current will result in a proportional increase in voltage.

The other formulas listed represent different concepts within electrical theory. For instance, V = WR pertains to work (W) done when an electric current flows over time, V = CQ relates voltage to capacitance (C) and charge (Q), and V = Pi connects voltage to power (P) and current (i). While all these equations involve voltage in distinct contexts, the equation V = iR specifically adheres to Ohm's law, making it the correct representation of voltage in relation to current and resistance.
