Q2. Types of Memory Allocations in C
Ans. 
Types of memory allocations in C include static, dynamic, and automatic.
• Static memory allocation: memory is allocated at compile time and remains constant throughout the program's execution. Example: int x = 5;

• Dynamic memory allocation: memory is allocated at runtime using functions like malloc() or calloc(). Example: int *ptr = (int*)malloc(sizeof(int));

• Automatic memory allocation: memory is allocated on the stack and...read more

Q3. Pointers in C - Types of pointers
Ans. 
Pointers in C are variables that store memory addresses. Types include null pointers, void pointers, function pointers, etc.
• Null pointers: int *ptr = NULL;

• Void pointers: void *ptr;

• Function pointers: int (*ptr)(int, int);

Q1. Difference between latch and flipflop
Ans. 
Latch is level triggered, while flip-flop is edge triggered. Latch is asynchronous, while flip-flop is synchronous.
• Latch is level triggered, meaning it changes output when the input signal is high or low continuously.

• Flip-flop is edge triggered, meaning it changes output only on the rising or falling edge of the clock signal.

• Latch is asynchronous, meaning the output changes as soon as the input changes.

• Flip-flop is syn...read more

Q2. Find the voltage through the resistor
Ans. 
To find the voltage through a resistor, use Ohm's Law: V = I * R
• Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor

• If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V

• Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts

Q3. The interviewer just kept on adding an extra resistor in parallel and in series to the resistor and asked me to find the voltage
Add your answer
Q4. He then asked a question on transient analysis ie 2 capacitors connected in series with a switch which closes at t>0 with the voltage across the 2 capacitors being 3 v and asked to find the total voltge

Q5. Explain the working of a capacitor and resistor and relation between resistance and length , area
Ans. 
Capacitors store electrical energy while resistors limit the flow of current. Resistance is directly proportional to length and inversely proportional to area.
• Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material

• Resistors limit the flow of current in a circuit by dissipating energy in the form of heat

• The resistance of a resistor is directly pr...read more
