Final Answer : C, Explanation :  In a series RC circuit, the voltage across the resistor (E_R) can be found using the formula E_R = E_T * (R / Z), where Z is the impedance. Z = √(R² + X_C²) = √(40² + 30²) = 50 Ω. Therefore, E_R = 240 * (40 / 50) = 192 V.

In a series RC circuit, E_T = 240 V, R = 40 Ω , and X_C = 30 Ω . What is E_R?

A) 144 V
B) 157.14 V
C) 192 V
