00:04Numerical number four of unit 19 electromagnetic induction is a transformer has 200 turns in the
00:14primary coil and 400 turns in the secondary coil if the primary voltage is 120 volt calculate the
00:25secondary voltage for a step of transformer so sb se phele hum data banayenge
00:36yahaan pere step of transformer ka kera hai to step of transformer me number of turns in secondary
00:43coil are more than the number of turns in primary coil number of turns in primary coil are given is
00:55two hundred turns
00:59or secondary coil me number of turns in
01:02oh four hundred turns given
01:08or voltage in primary is also given means vp voltage in primary ko vp ya e p se bhi
01:21hum denote kar sakte hai means
01:25e p r vp
01:29which is given
01:31which is 120 volt
01:35or hummeh kya calculate karne hai voltage in secondary means v s or e s
01:44so for solution
01:48or calculation we will use the basic equation of transformer is v s upon v p is equal to n
01:59s upon
02:01n p
02:03take a suppose this is the diagram for transformer
02:15so this is primary coil and this is
02:23second recoil so number of turns in primary coil and p are two hundred and number of turns in secondary
02:34means n s are
02:36four hundred and
02:38this is the pyramid
02:40jose voltage in primary
02:42which means vp
02:45means vp
02:46o
02:46and
02:46the
02:47which means
02:51vp
02:51you know
02:52and the
02:52and the
02:52and the
02:53and the
02:53and the
02:53and the
02:53and the
02:53and the
03:02as
03:03the
03:03vs will be equal to ns upon np multiplied with vp now by putting the given values voltage and
03:17secondary will be equal to number of turns in secondary are 400 divided by number of turns
03:25in primary number of turns primary is 200 so 200 multiplied with voltage in primary voltage
03:34in primary is also given which is 120 volt these two zeros will cancel the table of 2 on
03:442 is 1 times and on 4 is 2 times so 2 into 120 so it will be
03:55240 volt so voltage in secondary coil is obtained as 240 volts
