A circuit contains two devices that are connected in parallel. If the resistance of one of these devices is 12 ohms and the resistance of the other device is 4 ohms, the total resistance of the two devices is 3 ohms. Total resistance = 12*4 / (12+4) = 48/16 = 3.

Questions asked by the same visitor
1. A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. If the number of turns in the primary is 345, how many turns are in the secondary? A. 690 B. 1,653 C. 72 D. 8
Weegy: A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. [ If the number of turns in the primary is 345, There are 72 turns in the secondary. Solution: (V1/V2) = (T1/T2); (115/24) = 345/T2; 115T2 = 345 * 24; 115 T2 = 8280; T2 = 8280/115; = 72. ] (More)

A series circuit contains a generator, two devices, and connecting wires. The resistances of the two devices are 15 ohms and 10 ohms. The voltage supplied by the generator is 75 V. 30 V will be the voltage drop in the device with 10 ohms of resistance.

Solution: 75/(15 + 10) = 3V. per ohm. (3V x 10R) = 30V.
