  • Chapter 12: Fundamentals of Electricity & Electronics › Series DC Circuits › Determining the Voltage Divider Formula

    Determining the Voltage Divider Formula Figure 12-94 shows the example network of four resistors and a voltage source. With a few simple calculations, a formula for determining the voltage divisions in a series circuit can be determined. The voltage ... subscript x is the value of a particular resistor (1, 2, 3, or 4). Using Ohm’s Law, the voltage drop across any resistor can be determined. Figure 12-89. A voltage divider circuit. Figure 12-90. A typical voltage…

  • Chapter 12: Fundamentals of Electricity & Electronics › Capacitance › Voltage Rating of a Capacitor

    Voltage Rating of a Capacitor Capacitors have their limits as to how much voltage can be applied across the plates. The aircraft technician must be aware of the voltage rating, which specifies the maximum DC voltage that can be applied ... without the risk of damage to the device. This voltage rating is typically called the breakdown voltage, the working voltage, or simply the voltage rating. If the voltage applied across the plates is too great, the dielectric breaks down…

  • Chapter 12: Fundamentals of Electricity & Electronics › Series DC Circuits › Kirchhoff’s Voltage Law

    voltages have the same sign when added up. In the case of Figure 12-84, three cells of a value of 1.5 volts are in series with the polarity in the same direction. The addition is simple enough: However ... been turned around, and the polarity opposes the other two sources. Again the addition is simple: Kirchhoff’s Voltage Law A law of basic importance to the analysis of an electrical circuit is Kirchhoff’s Voltage Law. This law simply…
