...specially designed to have a low pre-determined Reverse Breakdown Voltage that takes advantage of this high reverse voltage . The zener diode is...
...enough energy to power a 100 watt lightbulb for just under two months. The voltage depends on the length of the bolt: with the dielectric breakdown of air being 3 million volts per meter, this works out at about...
Possible reasons: 1. defective dynamo cannot generate enough voltage to back charge the battery due to aging (usaully the internal rectifiers breakdown ) during running on the road and that it will fully exhaust the remaining...
... the switch is closed, pd btw the switch= voltage supply(E), because resistance(R) btw switch is...有火花(spark or electric arc)( electric field= pd/distance) (electric breakdown in air = 3x10^6 V/m) 這個火花當然要distance btw the...
1.(a) 47k Ohms, 10% (b) Resistance = 1/100 ohm = 0.001 ohm Hence, 0.001 = (2.825 x 10^-8)L/(1.5 x 10^-6) where L is the length of the wire solve for L gives L = 0.0531 m = 5.31 cm 2. and 3: can't see fig(a) and fig(b). 4. Let d be the original plate...
