node in question. Kirchhoff’s voltage law (KVL) describes a relationship among the voltages measured across the branches in any closed‚ connected path in a circuit. Each branch in a circuit is connected to two nodes. For the purpose of applying KVL‚ a path has an orientation in the sense that in “walking” along the path one would enter one of the nodes and exit the other. This establishes a direction for determining the voltage across a branch in the path: the voltage is the difference between the

LCD is used to display the measured voltage. The PIC microconotroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog input channels for the in-built 10-bit ADC. The voltage to be measured is fed to one of the 8 analog channels. The reference voltage for AD conversion is chosen to be the supply voltage Vdd (+5 V). A resistor divider network is used at the input end to map the range of input voltage to the ADC input voltage range (0-5 V). The technique is demonstrated

them in place of the standard resistor values throughout the remainder of the lab. Thevenin’s Theorem states that we can replace entire network by an equivalent circuit that contains only an independent voltage source in series with an impedance (resistor) such that the current-voltage relationship at the load is unchanged. Norton’s Thereom is identical to Thevenin’s Theorem except that the equivalent circuit is an independent current source in parallel with an impedance (resistor). Therefore
