Should costing is a process of estimating the manufacturing cost of a product based on its design, materials, and manufacturing processes.

• Should costing involves analyzing the design, materials, and manufacturing processes to determine the cost of producing a product.

• It helps in identifying cost-saving opportunities by comparing the estimated cost with the actual cost.

• Should costing can be used to negotiate better pric...read more

A zero watt bulb is a bulb that consumes zero watts of power when turned on.

• A zero watt bulb typically refers to an LED bulb that consumes very low power, close to zero watts, when turned on.

• These bulbs are energy efficient and have a very low power consumption compared to traditional incandescent bulbs.

• Zero watt bulbs are often used in applications where minimal power consumption is desired, such as night lights or in...read more

Resistance is the opposition to the flow of electric current through a conductor.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in the conductor.

• Resistance converts electrical energy into heat.

• Higher resistance leads to lower current flow.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

The faulty finding procedure for motor failure involves a systematic approach to identify and diagnose the cause of the failure.

• Start by gathering information about the motor failure, such as symptoms, error codes, and any recent changes or incidents.

• Perform visual inspections to check for any obvious signs of damage or malfunction, such as burnt components or loose connections.

• Conduct electrical tests to measure volta...read more

A temperature controller is a device used to regulate and maintain a desired temperature in a system or process.

• It measures the temperature using a sensor.

• It compares the measured temperature to a setpoint or desired temperature.

• Based on the comparison, it activates or deactivates a heating or cooling element to adjust the temperature.

• It ensures that the temperature remains within a specified range.

• Temperature controll...read more

A PID controller is a feedback control loop mechanism widely used in engineering to control systems and processes.

• PID stands for Proportional-Integral-Derivative.

• It continuously calculates an error value as the difference between a desired setpoint and a measured process variable.

• The controller then adjusts the control signal to minimize the error and bring the process variable closer to the setpoint.

• The proportional t...read more

Yes, I have a basic understanding of PLC (Programmable Logic Controller).

• PLC is a digital computer used for automation of electromechanical processes.

• It uses a programmable memory to store instructions and execute them in real-time.

• PLCs are commonly used in industrial settings to control machinery and processes.

• They can be programmed using ladder logic, function block diagrams, or structured text.

• PLCs can interface wit...read more

The formula for resistance is R = V/I, where R is resistance, V is voltage, and I is current.

• Resistance is the measure of opposition to the flow of electric current.

• The unit of resistance is ohm (Ω).

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• For example, if the voltage across a resistor is 10 volts and the current passing through it is 2 amps, the resist...read more
