Ohm's Law ની ગણતરી કેવી રીતે કરવી

Ohm's Law શું છે?

Ohm's Law relates voltage, current, and resistance in electrical circuits. This calculator solves for any one of the four quantities — voltage (V), current (I), resistance (R), or power (P) — given any two known values.

સૂત્ર

V = IR · P = IV = I²R = V²/R

પગલું દ્વારા પગલું માર્ગદર્શિકા

  1. 1Enter any two known values (V, I, R, or P)
  2. 2The calculator solves the remaining two using Ohm's Law and the power formula
  3. 3Results apply to DC circuits and to AC circuits at unity power factor

Worked Examples

ઇનપુટ
V = 12V · R = 47Ω
પરિણામ
I = 12/47 ≈ 0.255 A · P = 12 × 0.255 ≈ 3.06 W
A 1/4W resistor would overheat here — use at least a 1/2W rated part

Common Mistakes to Avoid

  • Applying Ohm's Law to non-linear components (diodes, transistors)
  • Forgetting unit prefixes: mA, kΩ, mW
