Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.see proper solving to nhi but aap impedance triangle banao aur cos phi nikalo to phi zero aa jaa rha and then eqn sin me rahnegi to us se aa jana hai d but let me try once
@hardcoreisdead here
i = i1+i2 ki jagah vector sum nahi hoga
since we are dealing with current as phasor
wave sum leke kar sakte hai
and waise bhi ye to humne simple i ka eqn nikala hai
i1 ya i2 alag chiz hai
when do we do vector sum then
Vo jab simple lcr ho
ye complex lcr hai
Yaha par parallel me connected hai
otherwise wave sum always works
why is AC so weird 🥀
nahh its easy
bas apna basics clear karlo
did u do complex numbers in maths?
i have but not used to their applications in AC
wait do jee teachers acc teach u how to use compl analysis to solve ac circuits?
aint no way
i wasnt taught but ik it can be used
ohh alr i would recommend using it sometimes incase u cant do some ques uing trad method
whats trad method
basically u treat impedane as a comple number (maybe thats why its written in z but who knows) where the real part is the value of resistor and the imaginary part is value of either inductor or capacitor
for inductor if value of XL is 5 then u write it as 5j where js is complex notation and in case of capacitors of capacitance 5 u write it as -5j now for effective z use same formulas as DC circuits 1/zeff = 1/z1+ 1/z2
in case of both resistor and cap/induc u write the z as R+XLj, i have showed how to use this in this que
and if u wna find i1 u can find like this ( i have used the property for inversion of a comple number which is 1/a+bj = a-bj/a^2+b^2
ok so Z = R + j ( XL-Xc) where symbols have usual meanings
yea
then treat everything like DC but w comple numbers
can we do like this
damn this is 🔥
where did u learn this
what is Y
yup
admittance
thats 1/Y btw
reciprocal of impedance
i watched a vid on yt yk theres a channel called electroboom that dude used sm shit liek comple numbers in electricity and i was like tf i gotta learn this shit so yea
lol
like padha kahan se
yt vid or some book
oh yt obv js watched few vids randomly and got it
comple number 10th me pada tha
yea or to find admitaance eff use Y1+Y2 ig
alr got it
thanxx
