1.Briefly discuss about Photo diode?
Photodiode:
A photodiode is a semiconductor device that converts light into an electrical
current. It operates based on the principle of the photovoltaic effect, where the
absorption of photons generates electron-hole pairs, leading to a current flow
when the device is connected in an electrical circuit.
Structure and Symbol:
*Structure: Photodiodes are made of semiconductor materials such as silicon.
They typically have a p-n junction, with the
science dna and rna
1. DNA STRUCTURE
-
-
-
Double helix: Twisted-ladder shape.
-
Nucleotide: Sugar (deoxyribose) + Phosphate + Nitrogenous base.
-
Bases: Purines (A, G); Pyrimidines (C, T).
-
Pairing: A–T (2 H-bonds), C–G (3 H-bonds).
-
Chargaff’s Rule: A=T, C=G.
-
Antiparallel strands: 5'→3' and 3'→5'.

1.8.COMPARE BJT AND FET?
A. Comparison between BJT and FET
| BJT (Bipolar Junction Transistor) | FET (Field Effect Transistor) |
|---|---|
| Current controlled (base current controls collector current) | Voltage controlled (gate voltage controls drain current) |
| Both electrons and holes contribute to current flow | Only majority carriers (electrons in N-channel, holes in P-channel) |
| Moderate input impedance | High input impedance (due to reverse bias on gate) |
| Relatively high power consumption | Relatively |

2.Draw the circuit diagram and explain the characteristics of BJT in CB configuration?
Characteristics ot BJT in CB Contiguration
The V-I characteristics of a BJT in the CB configuration describe the relationship
between the voltages and currents at the emitter and collector for various base
currents. These characteristics are divided into input and output characteristics.
1. Input Characteristics (Emitter-Base V-I Characteristics)
These characteristics show the relationship between the emitter
Organization Theory
ORGANIZATION THEORY
Study of how orgs function, structure themselves, make decisions, and interact with environment.
ORGANIZATION
Group of people working together to achieve common goals by coordinating resources.
PURPOSE OF ORGANIZATIONS
Achieve goals, create value, produce goods/services, adapt to environment, enable innovation, manage coordination.
TYPES OF ORGANIZATIONS
Profit: profit maximization via goods/services
Non-profit: social/service goals, no profit motive
Government: public service, policy

Q1) WAP that accepts the marks of 5 subjects and finds the Sum and Percentage
#include <stdio.h>
int main()
{
int marks[5];
int total = 0;
float percentage;
for(int i = 0; i < 5; i++)
{
scanf("%d", &marks[i]);
total += marks[i];
}
percentage = (total / 5.0);
printf("Sum: %d\n", total);
printf("Percentage: %2.f%%\n", percentage);
return 0;
}

1. Define Clipper, and explain clipping at two independent levels?
A.A clipper (also known as a limiter) is an electronic circuit used to remove or "clip" portions
of a signal that exceed a certain threshold voltage level without distorting the remaining
part of the waveform. Clippers are used in various applications, such as signal conditioning,
waveform shaping, and protecting circuits from voltage spikes
Clipping at Two Independent Levels:
Clipping at two independent levels involves limiting

1. V-I Characteristics of a PN Junction Diode?
A.The voltage-current (V-I) characteristics of a PN junction diode describe
the relationship between the voltage applied across the diode and the resulting
current that flows through it. This relationship is highly nonlinear and is typically'
divided into three regions: forward bias, reverse bias, and breakdown.
Forward Bias Region:In the forward bias region, the positive terminal of the voltage
source is connected to the p-type material, and
