Effortlessly Calculate Electrical Values with Cressall's Ohm's Law & Power Law Calculator

The Ohm's Law & Power Law Calculator by Cressall Resistors Ltd offers a straightforward tool for quickly determining voltage, current, resistance, and power, making it an invaluable resource for students and professionals alike.
Ohm's law and the power law describe the relationship between the following four electrical entities:
- Voltage - Unit: Volts; Symbols: V
- Current - Unit: Amps; Symbols: A, I
- Resistance - Unit: Ohms; Symbols: Ω, R
- Power - Unit: Watts; Symbols: W
Ohm's law: Voltage = Current x Resistance. Power law: Power = Voltage x Current. By setting any two of these entities, the other two can be calculated.
This application offers the functionality to lock one parameter while inputting another, facilitating swift "what-if" scenario calculations.
Utilize the keypad to enter a value and then tap on the parameter you wish to fix. Once locked, it will be indicated by a padlock symbol. Input another parameter, and the remaining two will be automatically calculated, with the most recently entered parameter becoming the newly fixed one.
You can change the fixed parameter by tapping on it when the input box is empty or by dragging the padlock to it. With a long press, you can 'Freeze' a parameter until it changes color, allowing alterations to the other three parameters. To unfreeze, tap any other parameter while the input box is empty.
The value of the fixed parameter cannot be modified. If an attempt is made, the padlock will flash, prompting you to fix another parameter first.
