When you are preparing to pass your electrical exam, you may wonder how to tackle the calculation-based questions on the test. While these questions can be challenging, but they are not impossible to solve if you learn how to apply winning strategies. Here are some of the best ways to answer calculation-based questions on the electrical exam.
Review the formulas and units.
Make sure you are familiar with the formulas and units that are referenced on the electrical exam. For example, you should know how to calculate voltage, current, resistance, power, energy, etc. You should also know how to convert between different units, such as volts, amps, ohms, and watts.
Read the question carefully.
When you encounter a calculation-based question, read it carefully and identify what information is given and what the question is asking for. Pay attention to the details and keywords that may indicate which formula or method to use. For example, if the question mentions parallel or series circuits, you should know how to apply Ohm’s law. If the question involves transformers, you should know how to use the turns ratio and the power equation.
Check your answer.
Always check your answer for reasonableness and accuracy. Compare it with the choices given (if it is a multiple-choice question) or with the expected range (if it is a numerical answer question). Make sure your answer is in the correct unit. If your answer seems too high or too low, or if it does not match any of the choices, go back and review your work. Look for any errors in your calculations, such as misplaced decimals, wrong signs or incorrect unit conversions.
Practice with sample questions.
The best way to improve your skills and confidence in answering calculation-based questions is to practice with sample questions that are similar to the ones on the exam.
