Voltage Divider

Electrical Laws and Formulas Voltage 

Voltage divider rule finds the voltage over a load in the electrical circuit, when the loads are connected in series. Voltage divider rule for DC circuit For a DC circuit with constant voltage source VT and resistors in series, the voltage drop Vi in resistor Ri is given by the formula:   Vi – voltage drop in resistor Ri in volts [V]. VT – the equivalent voltage source or voltage drop in volts [V]. Ri – resistance of resistor Ri in ohms [Ω]. R1 – resistance of resistor R1 in ohms [Ω]. R2 – resistance of resistor R2 in ohms [Ω]. R3 – resistance of resistor R3 in…

Solving Engineering Problems in Dynamics By Michael B. Spektor

Electrical Technology Mechanical Engineering Books 

INTRODUCTION Purposeful control and improvement of how existing mechanical systems perform is an important real-life problem, as is the development of new systems. We can obtain solutions to these problems by investigating the working processes of machines and their units and elements. These investigations should be based on fundamentals of dynamics combined with a variety of related sciences. The working processes that characterize system performance can be described by mathematical expressions that actually represent equations of motion of these systems. Analyzing these equations of motion reveals the relationship between the…
