None of the above” correct=”option2″]
The correct answer is: B. The total voltage is equal to the sum of the voltages across the resistance and capacitance.
In a parallel RC circuit, the voltage across the resistance and the voltage across the capacitance are in phase with each other, but they have different amplitudes. The total voltage is equal to the sum of the voltages across the resistance and the capacitance.
Option A is incorrect because the voltage across the resistance and the voltage across the capacitance are not always the same amplitude. Option C is incorrect because the total voltage does not lead the total current by less than 90 degrees. Option D is incorrect because the total voltage is not always less than the sum of the voltages across the resistance and the capacitance. Option E is incorrect because one of the above statements is true.
