Electricity stopped for 2,600 customers west of downtown Hamilton two Wednesdays ago after an unfortunate meeting of a bird and high voltage electricity.

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire—a solenoid.

I think I’d rather have the cheap one’s plastic case. That rubberized coating is probably going to deteriorate and get sticky, the way my Wacom pen’s grip did.

He notes that “current limiting on the driver board is set at 2,500 Amps, which may seem extreme for 600 Amp-rated transistors, but it’s pulsed.” RF potential on the primary of the coil (constructed from large diameter copper tubing) is estimated to be around 10,000 Volts.

And Brookfield Business Partners bought nuclear leader Westinghouse Electric from Toshiba for US$4.6 billion.

Abstract: A system and method to identify a call end associated with a problem that caused failure of an internet protocol-based call. The method includes accessing a first call detail record (CDR) set including at least one CDR associated with a first call end of the failed call, determining from the first CDR set indicators of failure attribution of the failed call, determining whether fault for failure of the failed call is attributed to the first call end based on the indicators of failure attribution; outputting an indication that the fault is attributed to the first call end if it was determined that the fault is attributed to the first call end, and outputting the indication to indicate the first call end is acquitted of the fault if it was determined the fault is not attributed to the first call end.

“The capacity of the batteries is measured in kilowatt hours (kWh), which is a metric of energy. The more the energy density can be increased in batteries, the higher the energy capacity for a given battery,” TechInsights’ Hines said. “For an EV, the design of a battery pack is limited by the size and mass of the pack. There is a certain amount where it’s not feasible to make it any bigger, because we are adding so much mass to the vehicle. The other performance metrics begin to suffer. Mass is the enemy of handling, acceleration and braking. The greater the mass, the harder it is to achieve good results on those performance metrics.”

Here C is the value of the capacitance in units of Farads—it also only depends on the physical configuration of the device.
