السلام عليكم ورحمة الله وبركاته ارجوا من الاخوة الذين لديهم الخبرة مساعدتي في حل هذه التمارين :
التمرين الاول :
mesh current method
you have to find equivalent resistance for the circuit from the parallell resistances R1=3K,R2=4K and resistances in series R3=1K, R4=2K.
3.you have to find unknown voltage Ur2 if Ur1=4V,Ur3=6V

==================================================
التمرين الثاني
1.write down the symbolic image of harmonic oscillation
\
2.find the module and phase of complex ersistance of impedor IF:
3.write down figure for amplitudes frequency characteristic and phase's frequency characteristic of cicuit .
