Summarizing, for any truly ohmic device having resistance R, V/I = ΔV/ΔI = R for any applied voltage or current or for the difference between any set of applied voltages or currents. The I–V curves of four devices: Two resistors, a diode, and a battery. The two resistors follow Ohm's law: The plot is a straight line through the origin.
The input voltage source and the resistor R constitute an imperfect current source passing current, I R through the load (Fig. 3 in the source). The INIC acts as a second current source passing "helping" current, I −R, through the load. As a result, the total current flowing through the load is constant and the circuit impedance seen by the ...
Shockley derives an equation for the voltage across a p-n junction in a long article published in 1949. [2] Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3]
Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
Bottom line. Savings rates have been trending downward, but there are still ways to maximize savings to buy a home. If you’re stressed about the next potential interest rate movement, McBride ...
(The Center Square) — In Louisiana, violent and property crime numbers across the state have dropped from recent years. Despite this, a survey earlier this year from the Manship School at LSU ...
An Oregon man was arrested and charged Thursday for the murder of a car dealership owner who disappeared three years ago, police said Monday. Murphy Henry, 54, was also charged with abuse of a ...
A schematic diagram of a voltage source, V, driving a resistor, R, and creating a current I. A voltage source is a two-terminal device which can maintain a fixed voltage. [1] An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply ...
