The voltage in the circuit is 120 V. The resistance of each of the two electric lamps included

The voltage in the circuit is 120 V. The resistance of each of the two electric lamps included in this network is 240 ohms. Determine the amperage in each lamp when they are connected in parallel.

The given voltage in the circuit is equal to 120 V. Resistance of the first lamp = resistance of the second lamp = 240 Ohm. It is necessary to find the amperage in each of the lamps when they are connected in parallel. Solution. When the lamps are connected in parallel, the voltage in the network is unchanged (Knowing that the resistance of the two lamps is equal). It follows that the current in the first lamp is equal to the current in the second lamp = voltage / resistance = 120/240 = 0.5A
