Working with electricity is not just about connecting physical wires and getting current to electrical devices.
There is a lot of maths involved and electrical contractors need to accurately calculate figures to ensure that the work they are doing will be able to support the end user’s operational requirements. Incorrect calculations could have catastrophic results – not just to infrastructure but possibly injury or worse to people nearby.
Thanks to developers like V Pugazhenthi, contractors and electricians do not need to pull out their pen and paper to start doing maths. Instead, smartphone apps like Ohm’s Law Calc put the power of instant maths equations into the palm of a professional’s hands, which is handy when they are on-site and need to quickly solve problems.
The free Ohm’s Law Calc app contains ads and there a few locked calculations (the ads can be removed and the calculations unlocked for a once-off payment of R79.99), but the main equations are free – there are 62 computations that can be calculated on the free version, ranging from a voltage calculator and power calculator, to the three-phase current calculator and even an energy cost calculator. All that the contractor needs to do is accurately enter the information required for the specific calculation and the Ohm’s Law Calc app instantly calculates the required information.
