Question 1 of 10
What unit is electric current measured in?
Electric current is measured in Amperes (Amps).
Question 2 of 10
What type of current changes direction continuously?
AC current continuously changes direction, while DC current flows in one direction.
Question 3 of 10
What is the primary tool used to measure current in a circuit?
A multimeter is the primary tool for measuring electrical quantities like current, voltage, and resistance.
Question 4 of 10
When measuring current, how should a multimeter be connected in the circuit?
A multimeter must be connected in series with the circuit to measure current.
Question 5 of 10
Before measuring current, what must you do to the circuit?
The circuit must be opened at the point of measurement to allow the current to flow through the meter.
Question 6 of 10
What should you do before disconnecting the multimeter from a circuit after measuring current?
Always turn off the power supply and remove the red probe first, then the black probe.
Question 7 of 10
Which socket on a multimeter is typically used for connecting the black probe?
The black probe is usually connected to the COM (common) socket.
Question 8 of 10
What precaution should be taken when working with AC mains voltage?
Safety precautions like wearing gloves are essential when working with mains voltage.
Question 9 of 10
What does FSD stand for when referring to analog multimeter ranges?
FSD stands for Full Scale Deflection.
Question 10 of 10
When using a multimeter to measure current, what should you do if the reading is off-scale?
If the reading is off-scale, you should decrease the current range for better accuracy.
