A student makes an inductor in lab by wrapping many turns of fine copper wire around a spool. a real inductor coil such as this will have some internal resistance as well as inductance.
The student measures L as follows. The coil is connected across a 6V DC battery and a current of 0.5 amps is obtained. then the coil is connected across a 24V rms source oscilating at 60 Hz and current of 0.8 A rms is measured. What is L?
