The output of 2-input OR gates is 0 only when its:
Correct answer: A. Both inputs are 0
- A. Both inputs are 0
- B. Either input is 1
- C. Both inputs are 1
- D. Either input is 0
Explanation
This is the correct answer. In an OR gate, the output is 0 only when both of its inputs are 0. If both inputs are 1, or if either input is 1, the output will be 1. The OR gate performs a logical OR operation, and it produces a 1 (high) output when at least one of the inputs is 1. If both inputs are 0, the output will be 0 (low). X= A+ B 0= 0 + 0

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
