Electronics Concepts and Applications Flashcard

Front

A circuit consists of a 12V battery and three resistors in series: 2Ω, 3Ω, and 5Ω. Using Ohm's Law, calculate the total current flowing through the circuit.

Front

Consider a circuit with a single loop containing a 10V battery, a 4Ω resistor, and a 6Ω resistor. Using Kirchhoff's Voltage Law, determine the voltage drop across the 6Ω resistor.

Back

6V

Front

A transistor is used in a circuit as a switch. Explain how the transistor operates in the saturation and cutoff regions to function as a switch.

Back

In saturation, the transistor is on; in cutoff, it is off.

Front

Compare and contrast AC and DC circuits in terms of their applications and efficiency in power transmission. Provide reasoning for why AC is typically used for power distribution over long distances.

Back

AC is used because it can be easily transformed to different voltages.

In digital logic design, explain how a multiplexer can be used to implement a simple logic function. Consider a 2-to-1 multiplexer and describe its operation.

Back

A multiplexer selects one of many inputs and forwards it to a single output line.
