• Voltage is the sum of current and resistance.

In a scenario where a PLC-controlled motor does not start, what strategic steps would you take to diagnose the problem?

• Immediately replace the motor.

• Check the PLC program, verify input signals, and inspect wiring connections.

• Increase the power supply to the motor.

• Wait for the motor to start on its own.

How does the law of conservation of matter apply to a chemical reaction in a closed system?

• Matter is created during the reaction.

• Matter is destroyed during the reaction.

• The total mass of reactants equals the total mass of products.

• The total mass of products is greater than the total mass of reactants.
