In RLC series circuit, I = 1a, ur = 15V, UL = 80V, UC = 60V are known?
U2=UR2+(UL-UC)2=152+202
The following 2 in the above formula means square
U=25V
How to calculate the resonant frequency (natural frequency) of the circuit when the resistor is connected in series with the inductance and then in parallel with the capacitor?
Inductance and capacitor are connected in parallel to form a resonant circuit. Whether there is resistance or not has no effect on the resonant frequency. If there is resistance, it will play a "damping role". The larger the resistance is, the faster the attenuation of oscillation amplitude is
When a circuit with inductance, capacitance and resistance resonates, when it is in series, the current is infinite. I see. Why is the voltage infinite when it is in parallel? I'm an amateur,
Could you please explain it in an easy way? Thank you
You are wrong. In series resonance, the current reaches the extreme value, not infinity. In parallel resonance, the voltage reaches the extreme value, not infinity, This is the same as pendulum or swing. It is determined by inductance, capacitance, circuit resistance, power supply voltage and so on. For example, if you play swing, the length of swing rope is certain, your weight is certain, and your strength is certain, then your swing height is certain
