Current is the flow of electric charge, while voltage is the force that drives this flow.
Current is measured in Amperes (A) and represents the rate of flow of electric charge.
Voltage is measured in Volts (V) and represents the force or pressure that drives the current.
Ohm's Law relates current, voltage, and resistance: V = I * R.
Higher voltage can cause higher current to flow through a circuit.
Current and voltage have
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two or more coils of insulated wire wound around a core
Primary coil receives electrical energy and induces a magnetic field in the core
Secondary coil receives the magnetic field and converts it back into electrical energy
Used in power distribution, voltage regulation, and iso...
An oscillator is an electronic circuit that produces a repetitive electronic signal, typically a sine wave or square wave.
Oscillators are used in electronic devices to generate clock signals, audio tones, and radio frequencies.
Common types of oscillators include LC oscillators, crystal oscillators, and voltage-controlled oscillators.
Oscillators are essential components in electronic systems for timing and signal genera
CRO stands for Cathode Ray Oscilloscope, a device used to display and analyze the waveform of electrical signals.
CRO is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.
It uses a cathode ray tube (CRT) to display the waveform of the electrical signal.
CROs are commonly used in laboratories, w...

I applied via Naukri.com and was interviewed in Jul 2024. There was 1 interview round.
To divide the frequency of the clock using 3, you can use a divide-by-3 counter circuit.
Use a divide-by-3 counter circuit to divide the clock frequency by 3.
Connect the clock signal to the input of the counter circuit.
Obtain the divided clock signal at the output of the counter circuit.
Example: If the input clock frequency is 12 MHz, the output frequency will be 4 MHz after dividing by 3.
Design a sequential circuit to detect the sequence 001001.
Use flip-flops to store the previous bits in the sequence
Implement a state machine with states corresponding to each bit in the sequence
Transition between states based on input and current state
Output a signal when the final state is reached
8085 microcontroller is a popular 8-bit microprocessor used in various electronic devices.
8085 microcontroller is an 8-bit microprocessor introduced by Intel in 1977.
It has a 16-bit address bus which can access up to 64 KB of memory.
The microcontroller has a set of registers, ALU, control unit, and instruction decoder.
It operates on a single +5V power supply and can run at a maximum clock speed of 3 MHz.

Wireless communication is the transfer of information between two or more points without the use of physical connection wires.
Uses electromagnetic waves to transmit data
Common examples include Wi-Fi, Bluetooth, and cellular networks
Allows for mobility and flexibility in communication
Transfer control is the process of transferring the control of a program from one part to another.
Transfer control involves changing the flow of execution within a program.
It can be achieved through various control structures like loops, conditional statements, and function calls.
Examples include using 'if-else' statements to decide which block of code to execute, or using 'goto' statements to jump to a specific part o
Frequency of clock 3 can be divided using a frequency divider circuit.
Use a frequency divider circuit to divide the frequency of clock 3 by a specific factor.
For example, a divide-by-2 circuit will halve the frequency of clock 3.
Choose the appropriate type of frequency divider circuit based on the required division factor.
