A 10 ohm resistor has a 5-A current running through it. What is the voltage across the resistor? Two resistors are connected in parallel with a 20-volt battery. The resistors have values of R1 = 22 ohms and R2 = 78 ohms. What is the current (in amps) in this circuit? Round ...
Change the transistor, use a Darlington MPSA13/KSP13. This circuit has a sweet spot when Vc=Vb, that is, when there is almost no idle current across the diode. But the diode has to feed the base too. A darlington makes both things possible because of its very high hfe. ...
(b) Calculate (voltages are across respective resistors, currents flow through their respective resisto R1= 24.8 ohms R2= 13.9 ohms R3= 25.5 ohms V1= 5 volts V2= 11.9 volts V3= 9.1 volts What is the current through the 13.9-ohm resisto...

, and the current is equal to zero. Hence power is also equal to zero, and no power dissipates from an open circuit. The resistance of an open circuit is explained in detail further below. Open Circuit Resistance The behavior of aresistoris given byOhm’s law. The voltage across the re...
Using Lenz's law, determine the direction of the current in resistorabin Fig. 3.23 when (a) switchSis opended after having been closed for several minutes. (b) coilBis brought closer to coilAwith the swich closed. ltbr> ( c) the resistance ofRis decreased while the switch remains close...
This change in emitter current develops a voltage drop ΔVO across the load resistance RL, where,ΔVO gives the output voltage of the amplifier. There is a negative sign because of the collector current gives a voltage drop across RL with polarity opposite to the reference polarity. The ...
A completely separate interesting point which I haven't seen noted yet: If you have two wires that are as close to identical as you can make them, but things weren't quite perfect and one is slightly lower resistance than the other, the lower resistance wire will draw more current, thus...
There's one DAC output that'll run at about 50-60khz, it'll go to a high output drive op amp, resistor, and capacitor (DC offset removal) into a coil to sense the resonant frequency (this is the really tricky part), another op amp will read the peaks of the sine wave and amplif...
