Since "Elektroteknika 1" is a standard course title in Albanian universities (and similar programs in the Balkans), the specific exercises often vary by professor or textbook. However, the core curriculum is universal.

This guide is structured to cover the standard topics found in an Elektroteknika 1 syllabus (DC Circuits). It breaks down the typical exercise types you will encounter and provides the formulas and methods required to solve them.

3.2 Teorema e Superpozicionit

Konsideroni një burim në të njëjtën kohë, ndërsa të tjerët zëvendësohen me qark të shkurtër (tension) ose qark të hapur (rrymë).

Ushtrimi full: Për qarkun e mësipërm, llogaritni rrymën ( I_3 ) vetëm nga ( U_1 ), pastaj vetëm nga ( U_2 ), dhe mblidhni rezultatet.

Ky ushtrim është i gjatë për t'u shkruar këtu, por parimi është: ( I_3^(1) = \fracU_1R_1 + (R_2 ), etj.

Exercise 3.1: Power Triangle

Problem: For the RL circuit above, calculate: pastaj vetëm nga ( U_2 )

• Active power ( P )
• Reactive power ( Q )
• Apparent power ( S )
• Power factor ( pf )

Solution:

1. Active power (W): [ P = I^2 R = (6.98)^2 \cdot 10 = 487.2W ] or ( P = V I \cos\phi = 230 \cdot 6.98 \cdot \cos(72.3^\circ) \approx 487W )
2. Reactive power (VAR): [ Q = I^2 X_L = (6.98)^2 \cdot 31.42 \approx 1531VAR ] or ( Q = V I \sin\phi \approx 230 \cdot 6.98 \cdot 0.953 \approx 1530VAR )
3. Apparent power (VA): [ S = V I = 230 \cdot 6.98 \approx 1605VA ]
4. Power factor: [ pf = \cos\phi = \cos(72.3^\circ) \approx 0.304 \ (\textlagging) ] ✅ Check: ( S^2 = P^2 + Q^2 \Rightarrow 1605^2 \approx 487^2 + 1531^2 )

4. Capacitive Circuit – Phase Lead

2.1 Ligji i Parë i Kirkofit (Ligji i Nyjeve – KCL)

Shuma e rrymave që hyjnë në një nyje është zero.

Ushtrimi 2.1 (Qark me 3 degë): Në një nyje hyjnë rrymat ( I_1 = 2A ) dhe ( I_2 = 3A ), ndërsa dalin ( I_3 = 4A ) dhe ( I_4 ). Gjeni ( I_4 ).

Zgjidhja: ( I_1 + I_2 - I_3 - I_4 = 0 \Rightarrow 2+3-4-I_4=0 \Rightarrow 1 - I_4 = 0 \Rightarrow I_4 = 1A ).
