Complex Impedance Measurement Device for Alkaline Batteries
... improved by increasing the value of the gain setting resistor (RFB) by multiplying the value with the inverse of the attenuation ratio. For example, if the excitation peak-to-peak voltage is attenuated by a factor of 2, the RFB value must be doubled so that the signal presented to the ADC stays the ...

Equivalent Meter Resistance - Courses
... looking at the expression for Req. In the limit that Rmv is infinite (an ideal voltmeter), Req = R2. Therefore a good voltmeter has a large equivalent resistance Rmv. Even if it does, however, there may be circumstances where we need to measure a voltage across a large resistance. In that case, we s ...

vs v2 - Courses - University of Houston
... In thinking about resistor combinations, we know that Req will be less than either R2 or Rmv. From the voltage divider equation we see that the voltage vmeas will therefore be less v2. This introduces an error in measuring v2. The error introduced by the voltmeter will be small if Rmv >> R2. This ca ...

... If three lamps are connected in series with a battery, they form a series circuit. Charge flows through each in turn. When the switch is closed, a current exists almost immediately in all three lamps. The current does not “pile up” in any lamp but flows through each lamp. Electrons in all parts of t ...

Approximate methods for poles/zeros computation
... There is only n=1 pole. The time constant associated with the pole is obtained by computing the equivalent resistance “seen” by the capacitance, setting the independent source to zero: τp=C(R1//R2) (Æ p=-1/ τp). From the definition, in order to find possible zeros in H(s)=(Vout/Vin) we seek a finite ...

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.The methods described in this article are only applicable to linear network analysis, except where explicitly stated.
