Mastering Elektroteknika 1: A Full Collection of Solved Exercises (Ushtrime të Zgjidhura)

Elektroteknika 1 is the foundation of every electrical and electronic engineering journey. While the theory (Ohm’s Law, Kirchhoff’s Laws, basic AC/DC) is crucial, the real mastery comes from solving problems—ushtrime.

This post provides a full walkthrough of typical exercises from Elektroteknika 1, covering DC circuits, basic AC, and power calculations.

3. Power in AC Circuits

Series Circuit (Rrotull)

  • Current: Same through all components ($I_total = I_1 = I_2$).
  • Voltage: Divides across resistors.
  • Formula: $R_total = R_1 + R_2 + R_3 + \dots$

Problem 2: Thevenin Equivalent

Given: Circuit with ( V_s = 24V, R_1 = 6\Omega, R_2 = 12\Omega, R_3 = 8\Omega ).
Load ( R_L ) connected across ( R_3 ). Find ( V_th, R_th ).

Solution:

  1. Find ( V_th ) = voltage across ( R_3 ) with ( R_L ) open.
    ( R_1 ) and ( R_2 ) in series: ( 6+12=18\Omega ).
    Total current from source: ( I = 24 / 18 = 1.333 A ).
    Voltage across ( R_2 ): ( V_R2 = 1.333 \times 12 = 16V ).
    That’s also voltage across ( R_3 ) (parallel branch open, no drop on R3).
    So ( V_th = 16V ).

  2. Find ( R_th ) – replace V_s with short.
    ( R_1 ) parallel with ( R_2 ): ( (6 \times 12)/(6+12) = 72/18 = 4\Omega ).
    That 4Ω in series with ( R_3 ): ( 4 + 8 = 12\Omega ).
    ( R_th = 12\Omega ).

Answer: ( V_th = 16V, R_th = 12\Omega ).

A. Ohm’s Law (Ligji i Ohmit)

This relates voltage ($V$), current ($I$), and resistance ($R$). elektroteknika 1 ushtrime full

  • Formula: $V = I \times R$
  • Derivations:
    • $I = \fracVR$
    • $R = \fracVI$

Typical Exercise:

  • Given: A resistor of $100\Omega$ has $12V$ across it.
  • Find: The current flowing through it.
  • Solution: $I = \frac12V100\Omega = 0.12A$ (or $120mA$).

Exercise 1.1: Finding Unknown Currents

Problem: In the circuit below (imagine a simple parallel-series circuit), we have:

  • ( V = 24V )
  • ( R_1 = 4\Omega ), ( R_2 = 6\Omega ), ( R_3 = 12\Omega ) Find the total current and the current through ( R_3 ).

Solution (Step-by-Step):

  1. Find equivalent resistance – ( R_2 ) and ( R_3 ) are in parallel: [ \frac1R_23 = \frac16 + \frac112 = \frac2+112 = \frac312 \Rightarrow R_23 = 4\Omega ]
  2. Total resistance (( R_1 ) in series with ( R_23 )): [ R_tot = 4\Omega + 4\Omega = 8\Omega ]
  3. Total current (Ohm’s Law): [ I_tot = \fracVR_tot = \frac248 = 3A ]
  4. Voltage across parallel branch (( R_23 )): [ V_23 = I_tot \cdot R_23 = 3 \cdot 4 = 12V ]
  5. Current through ( R_3 ): [ I_3 = \fracV_23R_3 = \frac1212 = 1A ] ✅ Answer: ( I_tot = 3A, I_3 = 1A )

Final Tips for Solving Ushtrime in Elektroteknika 1

✅ Draw the circuit clearly – label all nodes and components.
✅ Write known values next to the diagram.
✅ Use step-by-step reasoning – don’t jump.
✅ Check units – convert mH to H, μF to F, etc.
✅ Verify with power balance – power supplied = power consumed.
