Hello students here we have to calculate the emitter base and collector voltages for the voltage and current for the given transistor.
00:08
So here the vbe is 0 .8 volt.
00:18
Then we can calculate the other parameters.
00:24
First we have to write down the given values that is here they give us the independent current values of voltages that is v plus equal to 3 volt plus 3 volt and r1 equal to 8 .2 kilo ohm and we will have v minus equal to plus 1 .5 volt and r2 equal to 4 .7 kilo volt and here beta equal to 50 and vbe is 0 .8 volt.
01:11
So first we have to calculate the base current calculate base currents.
01:16
So here first current calculation so we can get base current ib equal to rb minus divided by r2.
01:38
So we will get ib equal to 1 .5 divided by 4 .7 into 10 power 3 that will give you 0 .319 milliampere.
01:53
So here we can write ib equal to 0 .319 milliampere and in second we can calculate the collector current that is ic.
02:10
So we know that ic equal to beta into ib.
02:18
So we will get 50 into 0 .319 into 10 power minus 3 that will you 15 .95 milliampere.
02:31
Then we can calculate the emitter current ie equal to ie equal to ic plus ib...
