What does the formula I x R represent?

The formula I x R represents the calculation of voltage in an electrical circuit, according to Ohm's Law. In this equation, 'I' corresponds to the current flowing through the conductor (measured in amperes), and 'R' denotes the resistance of the conductor (measured in ohms). By multiplying the current (I) by the resistance (R), you obtain the voltage (V) across the conductor. This relationship is fundamental in understanding how electrical circuits operate, as it helps to determine how much voltage is required to drive a given current through a specific resistance. This principle is essential for anyone working with fire alarm systems, as it aids in ensuring that devices receive the appropriate voltage for proper functioning.
