Weegy: 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.
Solution:
(R1R2)/(R1+R2);
( 12 * 4) / (12+4);
48/16 = 3 ohms. ]

User: If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V, the current flowing through the circuit is
Weegy: If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V, the current flowing through the circuit is 5 A.
User: 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?
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. ]
