How much voltage is dangerous is not really a static number as it depends on your body resistance, time of exposure and source "stiffness" (i.e. how much current it can supply). You get figures like 60V (or as low as 30V) which are an attempt at an average figure above which "caution should be taken". However, depending on how "conductive" you are at any one time, sometimes e.g. 50V might be ...
How would one go about using a 12 V DC power source to power something which needs 4.5 V DC using resistors? Is there a way to determine how much adding a resistor would drop the voltage?
You only stated one of the two critical facts about an ideal op amp. The voltage difference between the inputs is zero, and the input currents are also zero. Therefore, you can apply Kirchhoff's current and voltage laws to solve the rest of circuit. For practical purposes, just think of an ideal op amp as a magical device which makes the conditions at its inputs always true - just like an ...
How does an ideal op amp amplify a voltage input when the voltage ...
Robust systems often have several different power sources, and switches are implemented to separate the power supplies from each other to avoid damage. In most cases, multiple diodes are placed in the ...
Voltage references are available with fixed and adjustable reference voltage outputs. Adjustable output is set by a resistor divider connected to a reference pin. These references are either shunt ...
It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...
