Electric circuit
Figure 1 shows the intemal circuitry for a cellular phone charger prototype. You, the engineer, are
required to do an electrical analysis of the circuit by hand to assess the operation of the charger on
different loads. The two output teminals of this linear device are across the resistor, R5.
RS is not the load resistor. The load is not included in the circuit.
you decided to reduce the complex circuit to an equivalent circuit for easier analysis.
