Ohms law x: Calculating power with regards to P = IV, P = I2R, and P = V2 / R

components

Ohms law x is an open source app that is used to calculate any value with power and another value like resistance, current or voltage. It is also used to calculate power with just one value.

Proposals

I’ve used the app for a while, and I find it difficult to calculate power in terms of

• current and resistance
• Voltage and current
• Voltage and resistance

The app cannot be used to calculate the power in the circuit as you need to have a figure for power already before using the app. There’s a space that displays the three formulas of power (P = VI, P = I²R, P = V² / R), but the app can’t calculate power with respect to those formulas. It would be nice if this proposal is considered, and those ideas implemented.

Mocks up

The images below shows the current interface and the proposed one for the calculation of power regarding current and resistance, Voltage and current, Voltage and resistance.

Benefits

Since the app supports almost all ohms law calculation (basic ones), completing it with the proposed idea will add more value to it. Calculating power regarding current and resistance, Voltage and current, Voltage and resistance will be made easy, which will create a user-friendly environment for the users.
