App Reviews

Here’s what other app users say,

Absolutely Awesome! Perfect for Car Audio ! Equalise your amps! calculate Fuse rating ect. ect. love it!Great app so far compared to the rest of them.Does what it says. Xxx.This calculator is very simple and easy calculation.

CALCULATE VOLTAGE

This Ohms Law Calculator app is extremely easy to use,  just enter any two values and hit “Calculate” to calculate the other two.

 

Calculate:

  • Voltage (Volts)
  • Current (Amperes)
  • Resistance (Ohm’s)
  • Power (Watts)

 

Enter any two values to calculate the other two!

 

How to calculate voltage

Voltage = I x R
Current (I) x Resistance (I) = Voltage (V)

CALCULATE CURRENT

To calculate current with this ohms law calculator enter either two of theses options, voltage, resistance or power.

 

Ohm’s Law Symbols:

  • V = Voltage
  • I = Current
  • R = Resistance
  • P = Power

 

Enter any two of the above values to calculate the other two!

 

How to calculate current

Current = V ÷ R
Voltage (V) ÷ Resistance (R) = Current (I)

CALCULATE RESISTANCE

To calculate resistance enter any two of Voltage, Current or Power.

 

Ohm’s Law Measurements:

  • – Resistance is measured in Ohms (Ω)
  • – Voltage is measured in Volts (V)
  • – Power is measured in Watts (W)
  • – Current is measured in Amps (A)

 

How to calculate resistance

Resistance = V ÷ I
Voltage (V) ÷ Current (I) = Resistance (R)

CALCULATE POWER

To calculate power with this Ohm’s Law Calculator enter any two of theses options, Voltage, Current or Resistance.

 

Ohms Law Calculations:

  • Power
  • Amps
  • Resistance
  • Voltage
FREQUENTLY ASKED QUESTIONS

Ohm’s Law is a formula for calculating the relationships between Voltage, Current and Resistance.

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance one arrives at the usual mathematical equation that describes this relationship. Source: Wikipedia
