Using Ohm's law: I = V/R = 25/5 = 5A

Req = (R₁ × R₂)/(R₁ + R₂) = (6 × 12)/(6 + 12) = 72/18 = 4Ω

Power P = V²/R = (50)²/100 = 2500/100 = 25W

Energy stored E = ½CV² = ½ × 50×10⁻⁶ × (200)² = ½ × 50×10⁻⁶ × 40000 = 1J

In star connection, Vph = VL/√3 = 440/1.732 ≈ 254V

Norton equivalent current is equal to the short-circuit current measured between the terminals, which is 5A.

When considering only V₁ (V₂ is short-circuited), I₁ = V₁/R = 10/10 = 1A

The Wheatstone bridge is balanced when R₁ × R₄ = R₂ × R₃, resulting in zero galvanometer deflection.

KVL states that the algebraic sum of all voltages in a closed loop is zero, applicable to both AC and DC circuits.

Thevenin equivalent voltage is the open circuit voltage measured across the terminals, which is 8V in this case.
