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...read more

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

Q2. Types of rectifiers
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

Q3. Symbol of pnp and npn
Ans. 
The symbol of a PNP transistor is an arrow pointing out from the base, while the symbol of an NPN transistor is an arrow pointing into the base.
• PNP transistor symbol: Arrow pointing out from the base

• NPN transistor symbol: Arrow pointing into the base

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...read more

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...read more
