An application with useful tables and calculators for electricians and electronics. You will find in it calculators, ie Ohm's Law calculator, equivalent (parallel and serial) resistance, resistor selection for the LED diode or you can calculate how much you save by replacing the traditional bulb with an LED bulb. The application also includes tables such as electrical symbols, logic gates, wire markings, units, resistivity, radio waves, multiples, IP scale, antenna settings, fuse colors and resistor colors. The final element of the application is a theory that may prove useful during learning.
