Question 490Electricity & Electronics - Assistant Engineer

The correct answer is B) 10.00 ohms. To calculate the total reactance of the circuit, we need to use the formula for the combination of capacitive and inductive reactances in series: X_total = sqrt((X_L)^2 - (X_C)^2), where X_L is the inductive reactance and X_C is the capacitive reactance. Given: X_L = 40 ohms X_C = 30 ohms Plugging these values into the formula, we get: X_total = sqrt((40)^2 - (30)^2) = sqrt(1600 - 900) = sqrt(700) = 10.00 ohms. The other answer choices are incorrect because they do not correctly apply the formula for the combination of capacitive and inductive reactances in series.
