why??
Potentiometers are used as a
- variable voltage source.
- variable resistor.
- variable current source.
chevychase asking:
Potentiometers are used as voltage dividers are the not? they have 3 connections, surely a rheostat would be a better variable resistor?
Diodes connected in parallel would act like an
- an NAND gate.
- an AND gate.
- an OR gate.
azfar92 asking:
Why is the answer AND gate? For example,you put 2 diodes parallel to each other. If the current flow through one of the diodes,wouldnt the circuit is still complete?
