Series Resonant LCR Circuit
The impedance of LCR is In expression (1), I o has different values for different frequencies. But I o has a maximum value when Z is minimum. i.e., when X L = X L c or Z = R since w = 2 p f This frequency for which the current in AC circuit reaches a peak value and the A.C..

The weight w 1 of the weight hanger H is noted. A load of, say w 2 = 1kg is added to the hanger. Now, the tension in the string will be T = (w 1 + w 2 ) g newtons, where g is the acceleration due to gravity. The given tuning fork is struck on a hard rubber pad and the shank of the fork is press..
Alternating Currents Summary
Impedance triangle is a right-angled triangle whose base represents ohmic resistance R, perpendicular represents reactance (X L -X c ) and hypotenuse represents impedance (z) of the RLC circuit. From this triangle, we can calculate z and f as stated above. When a condenser of capacity C charged to ..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
