AC Circuit Resonance Given: F i n d : A I 9 . 3 ? max I v 103 max , GEN V mH L 9 . 2 F C 9 . 4 f f 2 max A generator with a variable frequency is connected to a resistor, capacitor, and an inductor with values as shown. The frequency is adjusted until the current is a maximum value of 3.9 A. Now the frequency is doubled. Find the new maximum current in the circuit. Solutions a.) To find we can use the following formula: max I the current is a maximum = resonant frequency or resonant LC 1 0 f f 2 max f f 2 2 max max LC f 2 2 2 2 0 max  I V R GEN max since 0 C L X X
