The SI unit of apparent power is the volt-ampere (VA).
Apparent power combines both the real power (which performs useful work) and the reactive power (which does not do useful work but is essential to maintain the electric and magnetic fields in the system).
The formula for apparent power \( S \) is:
\[
S = V \times I
\]
Where:
So, the unit of apparent power is the product of volts and amperes, which is volt-ampere (VA).
Apparent power combines both the real power (which performs useful work) and the reactive power (which does not do useful work but is essential to maintain the electric and magnetic fields in the system).
The formula for apparent power \( S \) is:
\[
S = V \times I
\]
Where:
- \( V \) is the voltage in volts (V),
- \( I \) is the current in amperes (A).
So, the unit of apparent power is the product of volts and amperes, which is volt-ampere (VA).
