Resistor Color Code Calculator

Accepts 4 arguments (first 3 bands determine resistor value, 4th band is for tolerance %), though none are required to return a value of 0 ohms. You must preserve order of bands as arguments.

resistor = Electric::Resistor.new("red", "black", "brown") resistor.value => 200 resistor.tolerance => "5%" resistor.human_readable => "200 ohms, +/- 5%"

Ohm's Law Calculator

Accepts 4 named arguments: "volts", "ohms", "amps", and "watts" in any order. You must provide at least 2 properties to calculate other 2.

There are 4 methods that can be called to run calculations: "resistance", "power", "voltage", and "current"

Electric::Ohm.new(:volts => 5, :ohms => 330).voltage => 5.0 Electric::Ohm.new(:volts => 5, :ohms => 330).resistance => 330.0 Electric::Ohm.new(:volts => 5, :ohms => 330).current => 0.015151515151515152 Electric::Ohm.new(:volts => 5, :ohms => 330).power => 0.07575757575757576
