Ans. 
A diode is a semiconductor device that allows current to flow in one direction only. AC can be converted to DC using rectifiers. Microprocessors process data using logic circuits. Transistors amplify or switch electronic signals. AC motors run on alternating current while DC motors run on direct current. Power supplies can work with both AC and DC inputs. Resistance is the opposition to the flow of electric current. Re...read more

Q2. How to work relay,
Ans. 
Relays are electrically operated switches used to control high power devices with low power signals.
• Relays consist of a coil, an armature, and one or more contacts.

• When current flows through the coil, it creates a magnetic field that attracts the armature, closing the contacts.

• Relays are commonly used in control circuits to switch high power devices such as motors, lights, and heaters.

• They can be used to isolate contro...read more

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
