Understanding Electrical Resistance     When it comes to electrical circuits, resistance plays a crucial role in determining how electricity flows. In the case of connecting four identical lamps in parallel, the total resistance is affected by the way they are arranged.     By utilizing the formula 1/RT = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn, we can calculate the total resistance. Given that the combined resistance of the four lamps is 100 ohms, we can deduce that the resistance of each lamp is 400 ohms.     Therefore, the resistance of one of the four identical lamps connected in parallel, when the total resistance is 100 ohms, is 400 ohms.
