JK Cement Instrumentation Technician Interview Questions and Answers

Concrete mix design involves determining the proportions of ingredients to create a specific concrete mixture.

• The mix design process considers factors such as strength, workability, and durability.

• Ingredients typically include cement, water, aggregates, and admixtures.

• The proportions of each ingredient are determined based on the desired properties of the concrete and the specific application.

• For example, a mix designe...read more

Electric current is influenced by various factors including voltage, resistance, and temperature, affecting its flow in circuits.

• Voltage: Higher voltage increases current flow, e.g., a 12V battery vs. a 1.5V battery.

• Resistance: Ohm's Law states that current is inversely proportional to resistance, e.g., a thick wire has less resistance than a thin wire.

• Temperature: Increased temperature can increase resistance in condu...read more

One ampere is a unit of electric current, representing the flow of one coulomb of charge per second.

• 1 Ampere (A) is defined as the flow of 1 Coulomb of charge per second.

• It is a fundamental unit in the International System of Units (SI).

• For example, a typical light bulb may use about 0.5 to 1 ampere of current.

• In household wiring, circuits are often rated for 15 or 20 amperes.

Electromotive force (EMF) is the energy provided per charge by a source, driving electric current in a circuit.

• EMF is measured in volts (V).

• It can be generated by batteries, generators, or solar cells.

• For example, a 12V car battery provides 12 volts of EMF.

• In a circuit, EMF causes current to flow through resistors and other components.

Electromotive force (EMF) is the energy provided per charge by a source, driving electrons through a conductor.

• EMF is measured in volts (V).

• It can be generated by batteries, generators, or solar cells.

• For example, a 12V car battery provides EMF to power the vehicle's electrical systems.

• In circuits, EMF causes current to flow, enabling devices to operate.
