    Peak current is the maximum current that flows through the circuit at the resonant frequency. It occurs when the capacitor is fully charged and the inductor is storing maximum energy. The peak current value can be calculated using the formula I=V/R, where V is the voltage across the circuit and R is the total resistance.

    www.physicsforums.com/threads/lipo-battery-peak-current-burst-c-rating.913046

    The LiPo battery peak current burst C rating is determined by multiplying the battery's capacity (in mAh) by its discharge rate (in C). For example, a 1000mAh battery with a 50C discharge rate would have a peak current burst C rating of 50A (1000mAh x 50C = 50A).

    www.physicsforums.com/threads/what-is-the-resonant-frequency-and-peak-current...

    The peak current drawn by a system is often highest at the resonant frequency. This is because at the resonant frequency, the system is vibrating with the greatest amplitude, which requires the most energy and results in the highest current draw. However, the peak current drawn can also be affected by the impedance and resistance of the system ...

  9. Help, RLC Circuit Problem - Peak Current At Resonance - Physics...

    www.physicsforums.com/threads/help-rlc-circuit-problem-peak-current-at...

    To calculate the peak current at resonance, we can use the formula I = V/R, where V is the peak voltage and R is the resistance in the circuit. In this case, the peak voltage is given as 100V and the resistance is 10 Ohms, so the peak current would be 10 Amps. I hope this helps you solve your homework problem.

    The square root of 2 (or approximately 1.414) is derived from the relationship between the peak value and the RMS value of a sine wave. When an alternating current or voltage is represented as a sine wave, the peak value refers to the maximum value of the wave, while the RMS value refers to the effective or average value of the wave.

  11. What is the peak current for this circuit? - Physics Forums

    www.physicsforums.com/threads/what-is-the-peak-current-for-this-circuit.757872

    Circuit Current Peak. In summary, the RLC circuit has a sinusoidal voltage supplied to it at 632 kHz with a peak voltage of 748 kV; a 25 kΩ resistance; a 16 µF capacitance; and a 30 H inductance. The peak current for this circuit can be found by dividing the peak voltage by the impedance, which results in a peak current of 26 μA.
