Calculate the value of the resonant frequency (in kHz) of a tank circuit having the capacitance of 0.01 mF and inductance of 0.01 mH?
Current through the 10Ω resistance I1 = V/R = 20/10 = 2A I1 = 2A Now current through the 20Ω resistance I2 = V − (-10)/R = (20 + 10)/20 = 1.5 A I2 = 1.5 A
If current flows for time t then the production of heat is given as H = I2R.t Where I = current = 1 A R = Resistance = 10 ohms t = time = 5 sec H = 12 × 10 × 5 H = 50 watt-sec or Joule
