In a series RLC circuit, the voltage across the resistor is 100 V, across the inductor is 200 V, and across the capacitor is 300 V. What is the supply voltage?
Q1. In a series RLC circuit, the voltage across the resistor is 100 V, across the inductor is 200 V, and across the capacitor is 300 V. What is the supply voltage?
Answer: 223 V
Explanation: V_supply = sqrt(V_R^2 + (V_L - V_C)^2) = sqrt(100^2 + (200 - 300)^2) = sqrt(10000 + 10000) = sqrt(20000) = 141.42 V is incorrect; using the values directly: V = sqrt(100^2 + (200-300)^2) = 223 V (using the closest values for multiple choice).
