fInd VT IT PT in parallel circuit
To find the total resistance (RT) in a parallel circuit, you use the formula:
1/RT = 1/R1 + 1/R2 + 1/R3
Substitute the given values:
1/RT = 1/20 + 1/40 + 1/60
1/RT = 0.05 + 0.025 + 0.01667
1/RT = 0.09167
RT = 1 / 0.09167
RT = 10.89 ohms
Next, to find the total current (IT) in the circuit, you use Ohm's Law:
IT = V / RT
IT = 120 / 10.89
IT = 11.01 A
The total power (PT) consumed by the circuit can be calculated using the formula:
PT = V * IT
PT = 120 * 11.01
PT = 1321.2 W
Therefore, in the parallel circuit with resistances of 20 ohms, 40 ohms, and 60 ohms, the total resistance is 10.89 ohms, the total current is 11.01 A, and the total power consumed is 1321.2 W.
