Question

A three-phase load has a phase voltage of 240 V and a phase current of 18 A. What is the apparent power of this load

Answer 1

The apparent power of a three-phase load can be calculated by multiplying the phase voltage by the phase current. In this case, the apparent power is 4320 VA (or 4.32 kVA).

Step-by-step explanation:

The apparent power of a three-phase load can be calculated using the formula:

Apparent Power (S) = Phase Voltage (V) * Phase Current (I)

In this case, the phase voltage is 240 V and the phase current is 18 A. Plugging in these values, we get:

Apparent Power (S) = 240 V * 18 A = 4320 VA (or 4.32 kVA)

Answer 2

7482.5VA

Step-by-step explanation:

We have that,

phase voltage of a three phase load is,240v

The phase current of a three phase load is, 18A

So To find apparent load we use

VA= √3*E*I

=√ 3*240*18

=7482.5VA
