Hi Folks,
I have a couple of questions I hope someone can answer.
Q1) If I connnect a DC supply across a
thermistor in series with a resistor
TAKE TEMP READING AS THE VOLTAGE DROP ACROSS Thermistor
WHICH IS BETTER TO USE ABOVE CIRCUIT OR THERMISTOR
IN A DC BRIDGE CIRCUIT, WHICH IS BETTER AND ????WHY?????
-----------------------------------------------------------------------------------
Q2) I need to switch on a SODIUM HIGH PRESSURE BULB
12hours ON
12hours OFF
If I use a relay, will the relay survive being on for 12hours at 240v @ 4A
Should I use a high power TRIAC??
Your opinion is always welcome!
