Both of those are much higher than the net 55ਹ of the dummy load. Of course those numbers are approximate, these are handy junk-box resistors. And of course all of this recklessly conflates DC resistance with RF impedance. But I'm not trying for NIST-traceable calibration, just ...
Replace the diodes with resistors and set their values according to how much light each one is receiving. I don't know what the transfer function of CdS etc., photoresistors are in terms of resistance vs. optical input power. If you can find that out and work out how much light or opt...

Two batteries, each rated for 12 V and 100 A.h are connected in series. What are the voltage and the charge of their series combination? Ten identical resistors connected in parallel have an equivalent resistance of 2 ohms. When they are connected in series, what will be its effective resi...
Termination resistors are strategically placed to absorb reflected signals, reducing the likelihood of ringing. Properly terminated transmission lines ensure uniform impedance throughout the transmission line. In this section, we will explore two widely used termination techniques: ...
EMIfilters are typically composed ofcapacitors,inductors, andresistorsthat are arranged in specific configurations to attenuateelectromagnetic interference. There are three basic types ofEMIfilters:single-stage, multiple-stage, and feed-through filters. ...
paragraph 4 (IV.10.4) of the chapter specifies the protective impedance device, stating that accessible conductive parts separated by double insulation may act as a conductive bridge using resistors or Y2 capacitors. They need to consist of at least two separate components of the ...
The output voltage (Vout) of the LM317 can be calculated through the two external resistors, R1and R2, using the formula: Vout= 1.25 * (1 + R2/ R1) Where: 1.25V is the reference voltage between the Adjust and Output pins. R1 is the resistor between the Output pin and the Adjust pi...
If you do not have access to a constant current electronic load, a purely resistive load made up of a network of high wattage resistors will do. Finally, the source of AC voltage for your PSU will come into play. The best configuration is an isolated transformer (1:1) in order to...
You can combine capacitors and resistors to form filters. A filter removes specific frequencies from an audio signal and lets others pass through. For example, if you want to remove high frequencies and let the lower frequencies pass through (e.g. in a sub-woofer), you can build a low-pa...
