If a current of 4 A flows into a bulb how much current flows out of the bulb
Answers
HEY MATE,FIRSTLY YOU WOULD HAVE TO UNDERSTAND THE PHENOMENON OF CURRENT IN BULB.LET ME EXPLAIN IT TO YOU.WHEN YOU INSERT CURRENT IN THE BULB THROUGH A WIRE MEDIUM,THEN THE CURRENT DIRECTLY GOES INTO THE BULB AND THE BULB USES THE CURRENT TO BE ENLIGHEN AND TO GLOW.ALSO HEAT IS PRODUCED IN THE PROCESS.BUT IF THE CURRENT HAS BEEN UTILISED,IT MUST ALSO BE RETURNED OUTSIDE.NOW,YOU WOULD WONDER HOW MUCH OF CURRENT WILL RETURN BACK?
LET ME TELL YOU,THAT THE SAME AMOUNT OF CURRENT INJECTED THROUGH A WIRE WILL RETURN BACK.WE HAVE ALSO A SCIENTIFIC REASON BEHIND IT.WHEN THE CURRENT IS INJECTED,IT IS UTILISED BY BULB,BUT NOT COMPLETELY....ALSO THE BULB PRODUCES THE SAME AMOUNT OF CURRENT AGAIN,EQUAL TO THE CURRENT IT HAS UTILISED....SO THE CURRENT INJECTED IS ALWAYS EQUAL TO THE CURRENT RETURNED.NOW LETS GO TO YOUR QUESTION...THIS WAS THE THEORITICAL PART...:D
ACCORDING TO THE QUERY,4A OF CURRENT IS INJECTED IN THE BULB,
I HAVE ALREADY TOLD THAT THE AMOUNT OF CURRENT INJECTED IS EQUAL TO THE CURRENT RETURNED IN THE THEORY PART ABOVE,AND WE HAVE BEEN ASKED WHAT IS THE CURRENT THAT FLOWS OUT (RETURNS) FROM THE BULB.....
SO I THINK NOW YOU MIGHT BE SURE THAT IT IS 4A.LET'S SEE THE IMAGE BELOW WHICH THOUROUGHLY EXPLAINS THE THEORY PART:
