This lab will require a power supply but what kind of power supply? This will be very important to the lab as the wrong power supply setting means a correctly assembled circuit will not work. (Note: depending on the edition of the lab manual this information can be found in the Basic Measurement or Simple Circuit lab write-ups.)

The correct answer will be "DC". The further explanation is given below.

Explanation:

Ohm's law, that also specifies that perhaps the flow of current via the capacitor is equal to the PD (potential difference) between the opposite edges including its conductor while the heat, as well as the other physical state of that same conductor, stay the very same. Throughout the experiment, this linear change in electrical current with such a PD is better identified by changing the difference unidirectional.

The linear or dimensional dependency of current onto PD wasn’t simple and easy to grasp. The supply voltage used would also be DC tube.
