You want to use a 5.0 Ω, 15 mA galvanometer coil as a 20 V voltmeter. What resistance should be placed in series with the coil? If each internal resistance is r=0.450 \; \Omega , and R = 4.00 \; \Omega , w...
If the current through the 213-Ohm resistor is 0.25 A, what is the current (in A) through the 221-Ohm resistor? I have a resistor of 230 ohms and apply a voltage across it of 9 volts. What is the current through the resistor...
Temperature compensation is provided by resistor 15: voltage stabilization of the 6 or 12 volt vehicle battery supply is effected by capacitor 18 and zener diode 19: preset resistor 11 is adjusted to allow the scale on meter 16 to read correctly for engines with different numbers of cylinders....
1. A system for controlling temperature-induced quality variation in a first filter disposed within a signal path, the system comprising: a second filter, disposed outside of the signal path, having an inductor, wherein a resistance of the inductor is temperature-dependent; a variable resistor,...
The cathode terminal of detector diode 254 is connected to the gate of power MOSFET 206 and also to a limiting resistor 256. The voltage generated across detector diode 254 turns on power MOSFET 206. When power MOSFET 206 is turned on, ignition coil 208 becomes charged and generates a spark...
