Question

A transistor cannot act as(a)anLED (b)an amplifier (c)an oscillator(d)a switch​

Answer 1

Explanation:

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number. Rationals are closed under addition (subtraction).

(A) an LED
