Voltage-current resistance or VIR triangle is a visual representation of Ohm’s law formulas.
The triangle illustrates the three formulas:
V = IR
I = V/R
R = V / I
Let’s understand these.
V = IR: Voltage is a product of current and resistance
I = V/R: Current is defined as the ratio of voltage to resistance
R = V/I: Resistance is defined as the ratio of voltage to current
