Question
**Problem 2: Analysis of a Y-connected Balanced 3-phase Source**

A Y-connected balanced 3-phase source supplies a balanced 3-phase load. The source phase A voltage and current are given as follows (note that phase angles are in radians):

\[
v(t) = 340 \cos(377t + 0.5236) \, V
\]

\[
i(t) = 100 \cos(377t + 0.87266) \, A
\]

**Tasks: Calculate the following for the source:**

a. **The phase voltage RMS value (V_phase_RMS)**

b. **The line-to-line voltage RMS value (V_line-to-line_RMS)**

c. **The phase current RMS value (I_phase_RMS)**

d. **The line current RMS value (I_line_RMS)**

---

**Explanation:** 

This problem involves finding the Root Mean Square (RMS) values for both voltage and current in a Y-connected 3-phase system. Typically, for a balanced Y-connected system, the RMS value of phase voltage and phase current can be derived from their peak (maximum) values. The relationship between phase voltage and line-to-line voltage is also essential in such systems, as is the relationship between phase current and line current in balanced loads.
