DC Circuits Relationships
Published in Muhammad H. Rashid, Ahmad Hemami, Electricity and Electronics for Renewable Energy Technology, 2017
A voltage divider is a circuit composed of series components that is used to provide one or more voltages from a single voltage supply. These voltages are lower than that of the power supply. This is not the most efficient way of obtaining a desired voltage from a power supply, but it is often the simplest or the easiest way. Suppose that you need 7.5 V for an application, but you have 12 V power supply. In such a case you may use a voltage divider to obtain 7.5 V from 12 V.
D.C. circuits and methods of circuit analysis

The voltage divider circuit is particularly useful when we need to obtain a potential difference which is a fraction of the voltage of an applied e.m.f. source. For example, the circuit of Fig. 1.13 has a potential difference VOUT between terminals C and D which is 1/1000 of the voltage VIN between points A and B.

Voltage dividers are a fundamental circuit building block, and we will encounter them in different forms at various points throughout this book. A voltage divider uses the ratio between two series resistors to divide a source voltage (Figure 3.6).
Waterproof, thin, high-performance pressure sensors-hand drawing for underwater wearable applications
Published in Science and Technology of Advanced Materials, 2021
On the other side, our method also desmonstrates the possibility of a fully integrated circuit that is created by hand-drawing and can work underwater. The circuit diagram can be seen in Figure 6(c-d). Herein, an Attiny85 works as a simple microcontroller unit. Two reference resistors (Rf) are 1–2 kΩ and drawn directly on the pyralux film by a pencil. One resistor used to protect the LED, and another resistor used to detect the change in the voltage divider circuit. As shown in Figure 6(e), the integrated circuit is programmed to turn on an LED when touching the sensor. Video S3 demonstrated the practical operation of this integrated circuit underwater. Two existing hard-components are the MCU and LED. However, this issue also opens a research direction for an all-hand-drawing-circuit in the future.

The DC discharge power was calculated as a product of voltage and discharge current, whereas the AC discharge power was estimated via modified Manley’s method.[17] The voltage across a capacitor was measured with a 100:1 voltage divider connected to the second channel of the oscilloscope. This voltage, representing the total charge in the EHD system, was plotted against the applied voltage. The area covered by the Lissajous (Bowditch) figure (Aliss) provided an estimate of the energy dissipated per cycle in Joules. The discharge power was calculated as Pd= Alissf, where f = 60 Hz is the alternating current frequency.

Inspired by Siegel’s design, a simple one-dimensional (1-D) resistor “network” is introduced. In this circuit, 33 identical resistors are connected in series to form a 32-channel network for each direction. For a single-channel input, the resistor network serves like a voltage divider. The relative ratio of signals from the two ends of the circuit, which are marked as A and B for the x-direction and C and D for the y-direction, has a linear relationship with the channel number. Specifically, the relationship is expressed as and
