Which one of the following statements is true for the voltages in a series RC circuit? A. The total voltage is equal to the sum of the voltages across the resistance and capacitance B. The voltage always has the same amplitude and phase for every part of the circuit C. The total voltage is less than the sum of the voltages across the resistance and capacitance D. The total voltage is greater than the sum of the voltages across the resistance and capacitance E. None of the above

The correct answer is: A. The total voltage is equal to the sum of the voltages across the resistance and capacitance.

In a series RC circuit, the current is the same through all components. The voltage across the resistor is in phase with the current, while the voltage across the capacitor is 90 degrees out of phase with the current. The total voltage is the sum of the voltages across the resistor and capacitor.

Option B is incorrect because the voltage does not always have the same amplitude and phase for every part of the circuit. The voltage across the resistor is in phase with the current, while the voltage across the capacitor is 90 degrees out of phase with the current.

Option C is incorrect because the total voltage is not less than the sum of the voltages across the resistance and capacitance. The total voltage is equal to the sum of the voltages across the resistance and capacitor.

Option D is incorrect because the total voltage is not greater than the sum of the voltages across the resistance and capacitance. The total voltage is equal to the sum of the voltages across the resistance and capacitor.

Option E is incorrect because the total voltage is equal to the sum of the voltages across the resistance and capacitance.
