I know that it is either current (I), voltage (V), or resistance (R) but I'm not sure which one it is.
sorry
Here we are given 3.1 amperes of current and are asked to find the time it takes 10 coulombs of charge to pass a given point. First ask yourself how many coulombs are passing a given point in one second. If we have 3.1 amperes of current, we have 3.1 coulombs of charge passing any given point in one second. If it takes 1 second for 3.1 coulombs of charge to pass, how long will it take for 10C of charge to pass?
That is 6 amps. One coulomb passing a point once a second is defined as one amp. Take the number of coulombs that have passed the point and divide it by the time it took the charge to pass (in seconds) and you have the current in amps.
Without some idea of the circuit surrounding R3, no answer can be given.

Hi pass says it passes higher frequency signals and blocks lower pass signals. This isn't typically a hard cutoff point but the lower frequency signals get attenuated over a frequency range. The R stands for resistance and C for capacitance such that these components are used to create the pass band for the circuit.

Frequency
The frequency of a wave is the number of waves that pass a point in a given amount of time, usually expressed in hertz (Hz).
The term for the amount of time it takes for one wave to pass by a given point is called the period. It is typically measured in seconds and is used to calculate the frequency of the wave.
The measure of the number of waves that pass a point in a given amount of time is called frequency. It is usually measured in hertz (Hz), where one hertz represents one wave passing a point per second.
The time it takes two successive crests of an ocean wave to pass a given point is called a wave period. It is typically measured in seconds and is inversely related to the wave frequency.
The time it takes for a wave to pass a given point is known as the period of the wave. It is the time it takes for one complete cycle of the wave to pass the point. The period of a wave is inversely proportional to its frequency.
The time it takes two successive crests of an ocean wave to pass a given point is called the wave period. It is measured in seconds and is an important parameter in describing wave characteristics like speed and frequency.
The number of complete waves that pass a given point in a certain amount of time is called the frequency of the waves. It is typically measured in hertz (Hz), which represents the number of complete wave cycles per second.

Those are called insulators.
