Hi, I am trying to make a power supply of 5 V as we all know it used a bridge circuit, then capacitors and LM7805 .
But i want to know how the valu of capacitance is calculated. What is tha formula for it?
If the formula is C=It/V
>Then what will be the value of 'I' and 'V'
>What is 't'?
I have 220V, 60Hz main supply. What are the calculations?
