A two-phase generator is connected to two 90 Ω load resistors. Each coil generates 120 V ac. A common neutral line exists. How much current flows through the common neutral line?
A. 1.33 A
B. 1.88 A
C. 2.66 A
D. 1.77 A
Answer: Option D
A. 1.33 A
B. 1.88 A
C. 2.66 A
D. 1.77 A
Answer: Option D
In a Y-connected source feeding a ∆-connected load,
A. Each phase of the load has one-third of the full line voltage across it
B. Each phase of the load has two-thirds of the full line voltage across it
C. Each phase of the load has the full line voltage across it
D. Each phase of the load has a voltage across it equal to $$\sqrt 3 $$
A. Single-phase 32 A; three-phase 16 A
B. Single-phase 16 A; three-phase 8 A
C. Single-phase 8 A; three-phase 4 A
D. Single-phase 16 A; three-phase 0 A
How to answer 1.77 but find the current value formula use the answer 1.33
