The ignition is cause by running 70 VDC through a 1/4 Watt 24 Ohm resistor. As you can see in ... We didn’t see a schematic, but he must have wired this so the system checks for continuity ...

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...
