what is the difference between electrical & electronics

Answer Posted / senthil kumar.a

in electonics we can control the flow of current bu another
one current (i.e we control the electricity by electricty)
for examle
in SCR we can control the flow of current BY APPLYING THE
GATE CURRENT . IT MEANS WE R CONTROL THE FLOW OF
ELECTRICITY BY CONTROLLING THE ELECRICTY OF GATE

IN CASE OF ELECTRICAL WE CANNOT DO THAT ABOVE

THE SWITCHES, RELAYS, CIRCUIT BREAKERS ARE CONTROL THE
CURRENT BY MECHANICAL ACTION ONLY.

THINK IT !!!!!!!!!!
