How can Venin's theorem be used to find the current io in a circuit?
A. By converting the circuit into its Thevenin equivalent and then calculating the current through the load resistor using Ohm's Law.
B. By applying Kirchhoff's Voltage Law to find the total resistance and then using the current formula.
C. By directly measuring the voltage across the load resistor and dividing by the total resistance.
D. By simplifying the circuit into a series of parallel resistors and calculating the current using the parallel resistor formula.
