Webb13 jan. 2024 · Ans: Yes, Kirchhoff’s laws fail at high frequency, because both the law \ ( { {\rm {KCL}}}\) and \ ( { {\rm {KVL}}}\) are not suitable for \ ( { {\rm {AC}}}\) circuits of high frequencies. At higher frequencies, the interference of induced emf due to varying magnetic fields becomes significant. Webb3 sep. 2024 · Correct answer: 2. 8 V. Solution: Resistor color coding: Red Yellow Brown Gray = 240 Ω ±10%. For resistor V = IR = 50 mA * 240 ohms = 12 V. Applying Kirchhoff’s voltage law: Σ Voltage rise = Σ Voltage drop. V 1 + 12 V = 12 V + 3 V + 5 V. V 1 = 20 V – 12 V = 8 V.
