How to size a rheostat
WebNov 25, 2024 · When you need to decrease the current in a circuit, you should increase the rheostat’s resistance. And just like that, if an increase in the current is demanded, you … WebSep 18, 2013 · When a logical input to the SN7407N is high, the output of its internal NOT gate is low. Since the output of the NOT gate is connected (through a resistor) to the base of the internal NPN transistor, the base of the transistor is held low. Under these conditions the NPN transistor could be described as “off,” since it does not conduct current.
