Just updated the two-resistor divider calculator to make the interface nicer (and the underlying code cleaner). Will update the three-resistor one after I do my taxes. Thanks, T3sl4co1l, for the links. I think jansson's is the closest to the design goals that I have for these calculat...
The signal is toggled approximately 2.5 ms after the 90% Vtt threshold is reached. This functionality is established with an RC circuit connected to the base of transistor A. As Vtt rises to regulation, the RC network (the 2.74 kΩ resistor, 22.1 kΩ resistor, and 1.0 µF capacitor)...
This calculator will determine the various design parameters for a zener diode resistor voltage regulator. Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By passing a small current through the diode from a voltage source, via ...
After being adjusted by the resistor 719, whose output point is electrically variable, VBE is input to the inverted input terminal 729 of the operational amplifier 713. A voltage Vout1which is input to the inverted input terminal 729, is input to the analog switch as Vout2after being adjuste...
The instantaneous voltage across the capacitor, across the resistor, and the current in the circuit at a selected time after the switch contacts position 2 can be calculated. This is best described using an example. The values calculated will be those present 30 milliseconds after the switch ...
Controller 902 can sense the rectified input voltage VΦR—IN in any desired manner, such as through a resistor divider circuit 905. Zero crossing calculator 904, which represents one embodiment of the zero crossing calculator 302 (FIG. 3), synthesizes the rectified input voltage VΦR—IN as...
Desktop VR11 systems use a pull-up resistor tied to the Vtt supply as an enable signal. Once the PWM Vcc voltage is above its under voltage lockout (UVLO) threshold, out of configuration states such as reset, and a valid enable signal is received, the PWM is to initiate the start up ...
you need to choose the direction of the current. in this problem, let us choose the clockwise direction. when the current flows across the resistor, there is a potential decrease. hence, v = ir is signed negative. if the current moves from low to high, then the emf (e) source is ...
