2.) Is the total concentration of current carriers (free electrons and holes) in a semicon- ductor equal to the concentration of valence electrons? 3.) There are two types of current carriers in semiconductors (free electrons and holes) and only one type in metals. Yet, metals are much better conductors of electric current. Is this because the currents of electrons and holes oppose each other?

Kirchhoff's first law or the junction law states that: the total current entering the junction is equal to the total current leaving the junction. This follows from the conservation of charge - charge cannot be created or destroyed. As a consequence, the charge entering the junction should equal the charge leaving the junction. The scenario below: 12 1₁ 13 follows Kirchhoff's junction rule violates Kirchhoff's junction rule as there is no outgoing current cannot determine whether it follows the junction rule or not without knowing the magnitude of the currents
The graph below shows the current that flows through a device called a diode at different voltages. Instead of the numbers presented on this graph, consider a diode for which current varies with voltage according to the equation I = V11.9. Hint: Plot this equation on your calculator. a.

IMPLEMENTATION OF XOR AND XNOR GATES USING NAND GATES 1. Material Required: Logic Trainer Connecting Wires Components(IC’s): 40112. Procedure:It is clear from the logic diagram that the NAND gate implementation of XOR gate requiresfive NAND gates. You will need two quad- 2 in NAND gate ICs to perform this experiment.Gets the required number of ICs containing NAND gates and other apparatus from the labattendant. Plug in the ICs in the breadboard of the Logic Trainer. Connect 5Vdc power supplyand ground on pins 14 and 7 respectively. For other pin configuration consult the data sheet (wehave already used NAND gates in the first lab so it should not be a problem). Wire your circuitaccording to the logic diagram for XOR gate as given above. Once you have wired the circuit,check it with your instructor and, if approved, power up your circuit. The outputs should beconnected to the LEDs on the Logic Trainer for monitoring purpose. Apply different inputcombinations at the input and note…
