Inrush current or input surge current refers to the maximum,
instantaneous input current drawn by an electrical device
when first turned on. For example, incandescent light bulbs
have high inrush currents until their filaments warm up and
their resistance increases. Alternating current electric
motors and transformers may draw several times their normal
full-load current when first energized, for a few cycles of
the input waveform. Power converters also feature high
inrush currents relative to their steady state currents

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
