Common questions

What is the Capacitance formula?

Capacitance is written C = Q/V. Capacitance is charge stored per unit voltage. It belongs to Electricity & Magnetism, under Capacitance.

What are the units in C = Q/V?

In SI units, C is capacitance, measured in A²·s⁴/(kg·m²); Q is charge, measured in A·s; V is voltage, measured in kg·m²/(A·s³).

How is the Capacitance formula derived?

C = Q/V by definition. The result is C = Q/V.
