Question

Which set of quantities describes the long solenoid used to derive its self-inductance?

Options

• Total turns \[N\], electric field, voltage, and resistance

• Length \[l\], cross-sectional area \[A\], total turns \[N\], and current \[I\]

• Cross-sectional area \[A\], resistance, voltage, and capacitance

• Length \[l\], electric field, voltage, and capacitance

Answer 1

The solenoid has length \[l\], cross-sectional area \[A\], and \[N\] total turns. A current \[I\] flows through it.
