Imagine you have been asked to measure the voltage of a battery using a multimeter, but you accidentally set the multimeter to the wrong range setting. How might this mistake affect your measurement results, and what steps could you take to correct the error?
The mistake would have no effect on the measurement results, as multimeters are designed to automatically adjust to the correct range setting.
The mistake would cause the battery to discharge more quickly, and to correct the error, you would need to recharge the battery before taking another measurement.
The mistake could cause inaccurate or unreliable measurement results, and to correct the error, you would need to select the correct range setting and take a new measurements
The mistake could damage the multimeter and render it unusable, and to correct the error, you would need to purchase a new multimeter
What is a resistor?
An electrical component that regulates the flow of current
An electronic device that generates electricity
A tool used to measure voltage
A device that stores electrical energy
What is the purpose of positioning the resistor with the gold or silver color band to the right when reading a 4 band resistor using the color coding chart?
To make it easier to read the colors
To ensure that the resistance value is read in the correct direction
To identify the wattage rating of the resistor
To correctly identify the tolerance of the resistor
Which of the following electronic equipment is used to drill holes in a PCB?
Electric Drill
Multimeter
Mini Drill
Signal Generator
Why is it necessary to switch off the selector knob of VOM after using it?
To recharge the multimeter
To drain the battery
To stop the battery from draining
To repair the multimeter
You are using an analog multimeter to test the voltage of an electrical circuit. What range should you start with to avoid damage to the multimeter?
The lowest range

Any range is fine
The highest range
Suppose you have just finished using a digital multimeter to measure resistance and are now putting it away. What should you do with the selector switch before storing the multimeter to preserve battery life?
Set the selector switch to the voltage measurement mode.
Leave the selector switch in the last-used resistance range.
Turn the selector switch to the OFF position
Set the selector switch to the highest resistance range.
