Q2. What is the column
Ans. 
A column is a vertical structural element that supports the weight of the structure above it.
• Columns are typically made of concrete, steel, or wood.

• They are used to transfer loads from the structure above to the foundation below.

• Columns come in various shapes and sizes, such as square, rectangular, or circular.

• Columns can be found in buildings, bridges, and other structures.

• Columns are essential for providing stability

Q3. What is the foundation
Ans. 
The foundation is the lowest part of a building, typically below ground level, that supports and anchors the structure.
• The foundation distributes the weight of the building and prevents settling or movement.

• There are different types of foundations, such as shallow foundations (e.g. strip, raft) and deep foundations (e.g. piles, caissons).

• The type of foundation used depends on factors like soil conditions, building size

Q1. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the driving force that pushes electric current through a circuit.

• It is measured in volts (V) and represents the potential energy per unit charge.

• Voltage can be positive or negative, depending on the direction of current flow.

• Higher voltage means more potential energy and can result in greater current flow.

• Examp...read more

Q2. 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.

• Current can be either direct current (DC) or alternating current (AC).

• In a series circuit, the current remains the same throughout.

• Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance.

Q1. What isOHM'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 = I * R, 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.

• For example, if a circuit has a vol...read more
