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.
Current
Frequency
"frequency"
A wave length.
"frequency"
Wave speed
Those are called insulators.
Frequency
...frequency.That's called the wave's frequency. Often measured in Hertz (Hz).
The Period
An infinite number of lines can pass through any given point.
You have no criminal record at this point. An acquittal means you were found not guilty of the charges.
