(a) Draw a neat diagram for a full wave rectifier circuit
(b) Draw the logic gate symbol and the truth table for a NAND gate with tow inputs
(c ) In an n-p-n tranasistor circuit the collector current is 10 mA if 95% of the enemitter current reach the collector what is the base current

Explanation

`I_(c ) = 10 mA`
`I_( b) = 5% I_(c ) = (5)/(100) xx I_(c )`
`=(5)/(10C) xx (100)/( 95) xx 10 = 0.52 mA`
