Specific resistance of conductors
... This question is a good review of the metric system, relating centimeters to meters, and such. It may also be a good review of unit conversions, if students choose to do their resistance calculations using English units (cmils, or square inches) rather than metric. Students may be surprised at the l ...

... flowing out of a node. Thus, the current flowing into node A must equal the current flowing out of node B. One way to demonstrate this is to assign values to the circuit components and, using Ohm’s Law, calculate the results. Thus, if the battery is equal to 100 volts, R1 equals 5 kΩ, R2 equals 50 k ...

19.3 Resistance and resistivity
... The ratio of the current in a conductor to the potential difference (voltage difference) between its ends is a constant as long as the temperature stays constant. This constant is called the RESISTANCE of the conductor. Resistance = Voltage (V)/Current(I) or R = V/I Voltage = Current x Resistance or ...

... for the -2824. The ratio of this factor at 1 GHz to that at 2 GHz is 0.30 for the -2800 and 0.48 for the -2824. This degradation factor also explains the increasing slope of the detection curve at higher values of frequency and diode capacitance. Consider the -2800 at 1 and 2 GHz. We have seen that ...
