A series LCR circuit carries the same current when the frequency of the source is $40$ Hz and when it is $90$ Hz. The voltage of the source has the same amplitude. What is the resonant frequency of the circuit?

← All Quizzes

← A voltage of frequency 25 Hz rises from zero as Vm sin ω t. How long after t = 0 does the voltage first reach 0.866 Vm?A series circuit has R = 4 Ω and XL = XC = 56 Ω at the frequency of its source, which gives 6 V (rms). What is the rms voltage across the capacitor? →
