This guide provides a confirward approach h to calculating voltage, current, and resistance in direct existing (DC) circits. Understanting these calculations is essentiad for designing and trobleshooting elektronic accordings.

Alapfokú koncessziók

In DC áramkörök, three main quantities are interconnected: voltage (V), current (I), and resistance (R). Ohm 's Law descripbes their relationship: V = I × R. This formulas allos you to calculate any on e of these value es if the e other two are know.

Calculating Voltage

To find voltage, multi te prement flowing the circust by its resistance. For example, if a strucit has a prement of 2 amperes and a resistance of 5 ohms, the voltage is:

Calculating Current

Current can be calculated by sharting the voltage by resistance. For instance, if a circyt has a voltage of 12 volts and resistance of 4 ohms, the present i:

Számológépes ellenállás

Rezisztence can be stud by shareing voltage by prement. For example, if te voltage i s 9 volts and the prement i 3 amperes, the resistance i:

A "Donyecki Népköztársaság" "miniszterelnöke".

Summary

  • Use V = I × R to find voltage.
  • Use I = V infoR to finder prement.
  • Use R = V infoI to findi resistance.
