    Application 1. What are the laws of series resistors? Of parallel resistors? Are these laws verified in your experiment? Ohm’s Law - Ohm’s law states that the voltage (V) across a resistor is proportional to the current (I)‚ where the constant of proportionality is the resistance (R). Series and parallel resistors - The total resistance of resistors connected in series is the sum of their individual resistance values. The total resistance of resistors connected in parallel is the reciprocal
