FAQs
Question: What is the formula for capacitance? Answer: The capacitance (C) is defined as the charge (Q) stored per unit voltage (V), given by the formula C = Q/V.
Question: How do capacitors behave in series and parallel circuits? Answer: In series, the total capacitance decreases, calculated using 1/C_total = 1/C1 + 1/C2 + ...; in parallel, it adds up: C_total = C1 + C2 + ...
