Question 1 of 10
When using a digital multimeter in resistance mode to test a capacitor, what reading indicates a good capacitor?
A good capacitor will initially show a brief resistance value and then display an open circuit (OL) on the multimeter.
Question 2 of 10
What is the primary function of discharging a capacitor before testing it?
Discharging is crucial for safety and accurate measurements, preventing damage to the meter and ensuring valid readings.
Question 3 of 10
In analog multimeter testing (Ohm mode), what does a very low resistance reading indicate about the capacitor?
A very low resistance suggests a direct path for current flow, signifying a shorted capacitor.
Question 4 of 10
What is the expected reading on a capacitance meter for a good capacitor?
A good capacitor will show a measured capacitance close to its specified value.
Question 5 of 10
When testing with a voltmeter, what does a voltage reading significantly lower than the applied voltage indicate?
A lower voltage reading indicates the capacitor is not storing the charge correctly, implying it is dead or has internal leakage.
Question 6 of 10
What is the formula for the time constant (?) in an RC circuit?
The time constant is calculated by multiplying resistance (R) by capacitance (C).
Question 7 of 10
What percentage of the applied voltage should a capacitor charge to after one time constant (?)?
A capacitor charges to approximately 63.2% of the applied voltage after one time constant.
Question 8 of 10
In the time constant method, what is the purpose of the known resistor?
The resistor limits the current flow, allowing the capacitor to charge at a manageable rate and prevents potential damage.
Question 9 of 10
Which multimeter setting is used for Method 5: Testing the Capacitor by Measuring the Time Constant?
Testing the capacitor by measuring the time constant uses voltage mode to determine the time taken to charge to 63.2% of the applied voltage.
Question 10 of 10
What does an 'OL' reading on a digital multimeter, when testing a capacitor in resistance mode, typically indicate?
OL (Open Line) means the resistance is too high to measure and implies a good capacitor which is not allowing the flow of DC current.
