What does the letter Q symbolize when measuring electrical charge?

Explanation:
Q represents electric charge. The unit of charge is the coulomb (C), so Q tells you how much charge is present. In circuits, current is the rate at which charge flows, described by I = dQ/dt. If you stack up individual charges, one coulomb equals about 6.242×10^18 elementary charges, and the total charge can be found with Q = n e, where e is the elementary charge (~1.602×10^-19 C). An electron is a particle that carries charge, but the symbol for charge itself is Q. Farad is the unit of capacitance, and Ohm is the unit of resistance.
