What does the letter Q symbol symbolize when measuring electrical charge?

Explanation:
Q stands for electric charge. The unit for charge is the coulomb, symbol C; one coulomb is the amount of charge that passes a point in a circuit when a current of one ampere flows for one second (Q = I × t). This distinguishes charge from voltage (potential difference, measured in volts), capacitance (farads), and energy (joules). So the symbol Q specifically identifies charge, making coulomb the correct unit for that quantity.
