VT?,IT, PT in parallel circuit
To calculate the total resistance (RT) in a parallel circuit, you can use the formula:
1/RT = 1/R1 + 1/R2 + 1/R3
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 = 10.91 ohms
To calculate the total current (IT) flowing through the circuit, you can use Ohm's Law:
IT = V / RT
IT = 120 / 10.91
IT = 10.99 A
To calculate the total power (PT) dissipated in the circuit, you can use the formula:
PT = IT^2 * RT
PT = 10.99^2 * 10.91
PT = 1202.099 W
Therefore, the total resistance (RT) is 10.91 ohms, the total current (IT) is 10.99 A, and the total power (PT) is 1202.099 W in the parallel circuit.
