You wish to invent a sparker for lightning gas burners. A 1.5-A current from a battery runsthrough a primary coil. When the switch in this circuit is opened, the current decreases to zero in0.60 ms, thus inducing a voltage in a secondary coil that causes a spark across a 0.50 mm gap.What must the mutual inductance be between the coils if the dielectric strength of the fumesbetween the gap is 2.4 x10 ^ V/m?
The figure shows an R-L circuit with a switch, a 166.7-9 resistor, an inductor and a 13.1-V battery.
When the switch is closed the current initially increases at 135.1 A/s. What is circuit's inductance (in
