[amp_mcq option1=”The voltage always has the same amplitude and phase for every part of the circuit” option2=”The total voltage is equal to the sum of the voltages across the resistance and inductance” option3=”The total voltage lags the total current by less than 90″ option4=”The total voltages is less than the sum of the voltages across the resistance and inductance E. 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 inductance.
In a parallel RL circuit, the voltage across the resistance and the voltage across the inductance are in parallel. This means that they add together to give the total voltage across the circuit. The total voltage is equal to the sum of the voltages across the resistance and inductance, regardless of the phase angle between the two voltages.
Option A is incorrect because the voltage across the resistance and the voltage across the inductance can have different amplitudes and phases.
Option C is incorrect because the total voltage can lag the total current by more than 90 degrees, depending on the values of the resistance and inductance.
Option D is incorrect because the total voltage can be greater than the sum of the voltages across the resistance and inductance, depending on the values of the resistance and inductance.
Option E is incorrect because the statement in option B is true.
