With Pullup Resistors on I2C Bus 2 Pullup Resistor Calculation A strong pullup (small resistor) prevents the I2C pin on an IC from being able to drive low. The VOL level that can be read as a valid logical low by the input buffers of an IC determines the minimum pullup resistance [RP(min)]. RP(min) is a function of VCC, VOL (max), and IOL: (1)

Series and Parallel Circuits Two resistors R 1 and R 2 are connected in series if all the current that passes through R 1 also passes through R 2.Therefore, for two resistors in series the current I 1 through R 1 is the same as the current I 2 through R 2, and this current is the same as the current, I, that enters the series network: I = I

resistors. The “resistance” network is essentially a serial connection to the ambient temperature. As a first approximation, the parallel-connected thermal resistance of the molding (broken lines) can be neglected in power packages. C The ambient temperature is represented by a voltage source. In accordance with the analogy, the thermal ...

EE 201 series/parallel combinations – 11 Since the calculation for parallel resistors, with the need for inverses, can be a bit messy, there are some short-cuts that can used for special cases. If there are only two resistors in parallel: (Product over sum, which might be easier to compute.) Two identical resistors, R 1 = R 2 = R: (e.g.

Series -Parallel Resistances Overview of Series-Parallel Circuits A series-parallel circuit, or combination circuit, combines both series and parallel connections. Most electronic circuits fall into this category. Series-parallel circuits are typically used when different voltage and current values are required from the same voltage source.

Ohm’s Law III—Resistors in Series and Parallel Resistors are manufactured in many different materials, forms, shapes, values, power ratings, and tolerances. While some resistor values are labeled with text, common resistors are color coded with bands to indicate their ohmic values. The color-numeric key is given in Table 1.

Series-Parallel Circuits • Series-Parallel circuits can be more complex as in this case: In circuit (a) we have our original complex circuit. In circuit (b) we have resistors R 1 and R 2 combined to get 13.2Ω. R 4 is in series with the newly combined R 12 and their added value is 51.2Ω. And now (c) we are left with R 124 in parallel with R 3.

For the parallel circuit, the battery voltage V o (.8R as calculated above) is the same as the voltage across each resistor (resistors in parallel have the same voltage across them). Using Ohm's Law on each of those resistors yields: V o = i 1 R = i 1 R. Putting in the voltage V o yields:.8R = i 1 R ⇒ i 1 = .8 amps.

Combination of Resistors If we put two resistors in series, then the mean square noise voltage is given by v2 n = 4kT(R1 +R2)B = vn21 +vn22 The noise powers add, not the noise voltages Likewise, for two resistors in parallel, we can add the mean square currents i2 n = 4kT(G1 +G2)B = i2n1 +i2n2 This holds for any pair of independent noise ...

If we arranged resistors in the same way as in Figure1, we would get the resistance, R eff = (R1 + R2) kR3 = (R1 + R2)R3 R1 + R2 + R3 which would change the analysis (we’d have to do everything over again). Instead, by making a series-parallel transformation, we can keep the same equation, which means all the analysis, and
