Question:
In delta connection, line current is related to phase current as
In delta connection, line current is related to phase current as
Show Hint
In delta connection, \(V_L=V_{ph}\) and \(I_L=\sqrt3I_{ph}\).
Updated On: May 27, 2026
- \(I_L=I_{ph}\)
- \(I_L=\sqrt3I_{ph}\)
- \(I_{ph}=\sqrt3I_L\)
- \(I_L=3I_{ph}\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
In a balanced delta-connected three-phase system, line current is \(\sqrt3\) times the phase current.
Step 1: In delta connection, phase voltage is equal to line voltage: \[ V_L=V_{ph} \]
Step 2: The relation between line current and phase current is: \[ I_L=\sqrt3I_{ph} \]
Step 3: Therefore: \[ \boxed{I_L=\sqrt3I_{ph}} \]
Step 1: In delta connection, phase voltage is equal to line voltage: \[ V_L=V_{ph} \]
Step 2: The relation between line current and phase current is: \[ I_L=\sqrt3I_{ph} \]
Step 3: Therefore: \[ \boxed{I_L=\sqrt3I_{ph}} \]
