Q1. What is ohm's law

Ans.

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
It is named after the German physicist...

Q2. What is impedance

Ans.

Impedance is the measure of opposition to the flow of alternating current in a circuit.

Impedance is a complex quantity that includes both resistance and reactance.
It is measured in ohms and is represented by the symbol Z.
Impedance can be calculated using the formula Z = R + jX, where R is the resistance and X is the reactance.
In AC circuits, impedance affects the flow of current and voltage.
Impedance matching is import

Q1. What is current

Ans.

Current is the flow of electric charge in a circuit.

Current is measured in Amperes (A).
It is the rate of flow of electric charge past a point in a circuit.
There are two types of current - direct current (DC) and alternating current (AC).

Q2. What is resistance

Ans.

Resistance is the opposition to the flow of electric current.

Resistance is measured in ohms (Ω).
It is caused by the collisions of electrons with atoms in a conductor.
Higher resistance leads to lower current flow.
Resistance can be affected by factors like material, length, and temperature.
Examples of high resistance materials include rubber and glass.
Examples of low resistance materials include copper and silver.

Q3. What is impedance

Ans.

Impedance is the measure of opposition to the flow of alternating current in a circuit.

Impedance is a combination of resistance, inductance, and capacitance in a circuit.
It is measured in ohms (Ω).
Impedance can be represented as a complex number with a real part (resistance) and an imaginary part (reactance).
Impedance affects the flow of current in a circuit, influencing voltage and current relationships.
Example: In an...

Q4. What is voltage

Ans.

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

Voltage is the force that pushes electric current through a circuit
It is measured in volts (V)
Voltage is the potential difference between two points in a circuit
Higher voltage means more potential energy available to move electrons
Example: A battery provides voltage to power a light bulb

Q5. What is Ohm's law And relation with voltage andcurrent

Ans.

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given a constant resistance.

Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It shows the relationship between voltage, current, and resistance in an electrical circuit.
If the voltage increases, the current will also increase if the resistance remains cons...

Ans.

Rectifiers are electronic devices used to convert alternating current (AC) to direct current (DC).

Types of rectifiers include half-wave, full-wave, and bridge rectifiers
Half-wave rectifiers only allow one half of the AC waveform to pass through
Full-wave rectifiers allow both halves of the AC waveform to pass through
Bridge rectifiers use four diodes to convert AC to DC more efficiently
Other types of rectifiers include c
