1. The problem statement, all variables and given/known data In the tuned circuit below, what will happen to the reading of the ammeter when: a) source frequency increases. The voltage is constant b) the capacitance increases. The voltage and source frequency are constant c) The voltage increases. Source frequency is constant. 2. Relevant equations ƒ =1/(2π√LC) Where: C is the capacitance and L is the inductance. I= V/Z Where: V is the voltage and Z is the impedance. Xc=1/ωC Xl=ωL Z=√R²+(Xl-Xc)² 3. The attempt at a solution Here is my solution: a) the ammeter reading decreses. Explanation: when source frequency varies the circuit is no longer in resonance so the impedance increases, Z=√R²+ (Xl-Xc)² b) the ammeter reading decreases. Explanation: when the capacitance C increases, Xc decrease, then (Xl-Xc) increses, hence the impedance increases because: Z= √R²+(Xl-Xc)² c) the ammeter reading increases. Explanation: since source frequency is constant, the circuit is still in resonance. So, increasing in voltage will increase the current becuase the impedance of the circuit will not change. Am I correct?
