Question

Changes in Vcc changes the value of V+?

(a) true

(b) false

(c) cant be said

(d) depends on the conditions

I had been asked this question in examination.

I'd like to ask this question from Comparator in chapter MSP430 Microcontroller of Microcontroller

Answer 1

Correct answer is (a) true

To elaborate: When some variation is made in the value of Vcc, in the same manner, itself the value of the V+ changes because, the voltage from the potential divider is proportional to Vcc. This changing effect can be reduced if the similar change takes place in the value of V- itself.
