The electrosurgical system includes at least one electrosurgical electrode 3 having a resistive element and a capacitive element configured in series. The electrosurgical system also including an electrosurgical generator 20 configured to generate electrosurgical energy having a first frequency which generates a first impedance in the at least one electrode due to capacitive reactance of the capacitive element in series. The generator 20 is further configured to adjust the first frequency to at least one other frequency to generate a different impedance in the at least one electrode 3 due to capacitive reactance of the capacitive element in series, thereby adjusting the temperature of at least one electrosurgical electrode 3.1/3 42 0 3 -, 2 p (P ELECTROSURGICAL GENERATOR 86 FIG. 1A 100 8064 0 110 74 120 lo 62 T FIG. 18213 100110 116 112 114 64 46 160 48 122 124 120 126 FIG. 2 ,-20 i---27 28 CONT ROLLER HVSRF QUT PUT 25-HVP ST AGE )_132 MICROPROCESSOR 22 26-,\ SENSOR MEMORY CIRCUIT R FIG. 3
