What is the formula for the total inductance of inductors in series?

• L_total = L1 + L2 + L3 + ... + Ln

• L_total = 1/(1/L1 + 1/L2 + 1/L3 + ... + 1/Ln)

• L_total = L1 * L2 * L3 * ... * Ln

• L_total = (L1 + L2 + L3 + ... + Ln)/n

In a series circuit, the current through all inductors is the same. True or False?

• True

• False

Voltage across inductors in a series circuit:

• is the same across each inductor

• divides proportionally to their inductance

• is zero

• depends on the resistance
