With a limiting resistor, the amount of current such a varying load draws will change as the effective resistance changes. But with our simple transistor circuit, 20 mA will always flow. Well ...

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient ... “Each resistor is simple and kind of meaningless on its own,” says ...

That is, a 1 KΩ and a 2 KΩ resistor in series will draw as much current as a 3 KΩ resistor. ... What a cool way to show an application of simple circuits! Report comment. Reply.

First, the detection impedance requires only one resistor with a value between 19 kΩ. and 26.5 kΩ.. Resistor R51 (Figure 5) draws a current close to the minimum expected of a valid impedance, to ...

The transistor is designed as a “controlled resistor” forming one part of a balanced bridge circuit. The base of T1 is directly connected to the receiving antenna. With increasing radio frequency ...

If our example resistor ended in gold (orange, white, black, gold), its 39 Ohms value could be five percent higher or lower. For a possible minimum of 37.05 or a maximum of 40.95.

A simple circuit addition helps reduce average power used in relay coil. ... the relay circuit draws around 58 mA. With the resistor/capacitor addition the steady state current is only 20 mA, ...
