Question

question 17
the total inductance value of a 2 h coil and a 4 h coil connected in series is ____.
6 h
1.2 h
2 h
8 h

Explanation:

Step1: Recall series inductance formula

For inductors in series, the total inductance \( L_{total} \) is the sum of individual inductances. The formula is \( L_{total}=L_1 + L_2 \).

Step2: Substitute values

Given \( L_1 = 2\space H \) and \( L_2 = 4\space H \), substitute into the formula: \( L_{total}=2 + 4 \).

Step3: Calculate the sum

\( 2+4 = 6 \), so \( L_{total}=6\space H \).

Answer:

A. 6 H
