Resistivity is measured in ohm-meters (Ω·m), indicating how strongly a material opposes electric current.
Resistivity (ρ) is defined as resistance per unit length and cross-sectional area.
Common units: 1 Ω·m = 1 ohm × meter.
Conductors like copper have low resistivity (~1.68 × 10^-8 Ω·m), while insulators like rubber have high resistivity (~10^13 Ω·m).
Resistivity varies with temperature; for example, the resistivity...
A semiconductor is a material that has electrical conductivity between a conductor and an insulator.
Semiconductors are used in electronic devices like transistors, diodes, and integrated circuits.
They have a band gap that allows them to conduct electricity under certain conditions.
Common semiconductor materials include silicon, germanium, and gallium arsenide.
Circuit theory problems involve analyzing electrical circuits using laws and theorems to find voltages, currents, and resistances.
Use Ohm's Law (V = IR) to relate voltage, current, and resistance.
Apply Kirchhoff's Voltage Law (KVL) to find the sum of voltages in a closed loop.
Utilize Kirchhoff's Current Law (KCL) to analyze current at junctions.
Example: In a series circuit, total resistance is the sum of individua...
A flip flop is a digital circuit that stores a single bit of data using two stable states.
Flip flops are used in digital electronics to store data and synchronize signals.
They can be edge-triggered or level-triggered.
Examples include D flip flop, JK flip flop, and T flip flop.
An array program involves manipulating a collection of strings or values stored in a list-like structure.
Arrays are used to store multiple values in a single variable.
Elements in an array are accessed by their index, starting from 0.
Common operations on arrays include adding, removing, and accessing elements.
Example: ['apple', 'banana', 'orange']
Pointers in programming are variables that store memory addresses, allowing for efficient data manipulation.
Pointers can be used to dynamically allocate memory. Example: int *ptr = (int*)malloc(sizeof(int));
They can point to arrays, enabling easy traversal. Example: int arr[] = {1, 2, 3}; int *p = arr;
Pointers can be used to pass large structures to functions without copying. Example: void func(MyStruct *s);
They c...

- Q1. What is diode? Why use in circuit
- Ans.
A diode is a semiconductor device that allows current to flow in one direction only. It is used in circuits to control the direction of current flow and to rectify AC to DC.
Diodes are used to protect circuits from reverse polarity, preventing damage to sensitive components.
They are used in rectifier circuits to convert AC voltage to DC voltage, such as in power supplies.
Diodes are also used in signal processing circuit...
