it is a circuit consist of three items current, volt and
resistance to be easy for anyone to calculate any item
Use the circle by covering the unknown value with a finger. (Example if the unknown value is Voltage - cover the "E" the equation remaining is I x R).
Ohm Circle is the drawing presentation in a circle divided into quadrants of the Power P, Resistance R, Volts V, and Current I, where you can derive the equations for each of the quantities in the form of the given combination formula. Its is comparative to Ohms Law Triangle for Resistance R, Voltage V, and Current I.
Ohms law gives relationship between Voltage, Current and Resistance. The ohm’s law was given by a German mathematician and physicist Georg Ohm. He published his measurements in1827 of applied voltage and current through electrical circuits containing various lengths of wire.
