What happens when expanding lines of force have motion relat

What happens when expanding lines of force have motion relative to a conductor? Voltage is induced resistance is reduced current is increased power is increased An inductor is rated by a unit names? Pated Lenz Ohm Heavy Calculate the voltage drop across a 10-Henry inductor when I_DKLZA/t_DKLZA is equal to 1 m/s: 100 volts 10 volts 45 volts 50 volts Inductance is the ability of a coil to oppose: current change voltage change voltage current The formula to determine total inductance when inductors are connected in parallel is similar to: series inductors series capacitors series resistors parallel capacitors What is the approximate time for a complete decay of 400 m lambda of inductor current, when R = 10 ohms and L = 20 H? 8 second 4 seconds 2 seconds 10 seconds What is the phase angle in a purely inductive circuit? Zero degrees 45 degrees 180 degrees 90 degrees What is the inductive reactance of a 1 mH coil, when the applied frequency is 15 kHz? 14.2 ohms 9.42 ohms 0.942 ohms 942.0 ohms
