Calculate VT,IT PT IN Parallel circuit
To calculate the total voltage (VT) in a parallel circuit, we can use the formula:
1/VT = 1/V1 + 1/V2 + 1/V3
Given:
V1 = 20V
V2 = 40V
V3 = 60V
1/VT = 1/20 + 1/40 + 1/60
1/VT = 0.05 + 0.025 + 0.01667
1/VT = 0.09167
VT = 1 / 0.09167
VT ≈ 10.89 V
Next, to calculate the total current (IT) in a parallel circuit, we can use the formula:
IT = I1 + I2 + I3
Given:
R1 = 20 ohm
R2 = 40 ohm
R3 = 60 ohm
Using Ohm's Law (V = IR):
I1 = V1 / R1 = 20V / 20 ohm = 1A
I2 = V2 / R2 = 40V / 40 ohm = 1A
I3 = V3 / R3 = 60V / 60 ohm = 1A
IT = 1A + 1A + 1A
IT = 3A
Finally, to calculate the total power (PT) in a parallel circuit, we can use the formula:
PT = VT * IT
PT = 10.89V * 3A
PT = 32.67W
Therefore, the total voltage (VT) is approximately 10.89V, the total current (IT) is 3A, and the total power (PT) is 32.67W in the parallel circuit.
