Using a sense resistor is only the first step in the current-sensing decision. The other part is topology: whether to use ...

[FesZ] shows how many meters measure voltage across a known resistor and the unknown so that a precision voltage or current source isn’t necessary. But there are a number of problems with this ...

Explore snubber circuits and their vital role in protecting semiconductor switches from voltage spikes and ringing.

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

Why a precision preamplifier is critical to low-side current-sensing performance.

The resistance of the resistor remains the same. We can calculate the voltage across the thermistor now using the same method. Find the total resistance of the voltage divider.

By adding a 15 V Zener diode and a resistor across the MOSFET which dims the LEDs, a voltage of around 9 V can be put across the LEDs without lighting them up when the MOSFET PWM dimmer is in its ...
