What is the inductance of three 10 millihenry inductors connected in parallel?
0.30 Henrys
3.3 Henrys
3.3 millihenrys
30 millihenrys
The correct answer is: 3.3 millihenrys
To determine the inductance of inductors connected in parallel, you need to apply the formula for combining inductors in parallel. For n inductors with the same inductance value (L), the total inductance (L_total) can be calculated using the formula: \[ \frac{1}{L_{\text{total}}} = \frac{1}{L_1} + \frac{1}{L_2} + \frac{1}{L_3} \] Given that all three inductors each have an inductance value of 10 millihenries (mH), the formula simplifies to: \[ \frac{1}{L_{\text{total}}} = \frac{1}{10 \, \text{mH}} + \frac{1}{10 \, \text{mH}} + \frac{1}{10 \, \text{mH}} \] Calculating this gives: \[ \frac{1}{L_{\text{total}}} = \frac{3}{10 \, \text{mH}} \] Thus: \[ L_{\text{total}} = \frac{10 \, \text{mH}}{
