An XOR gate produces an output only when its two inputs are:
Correct answer: C. Different
- A. High
- B. Low
- C. Different
- D. Same
Explanation
This is the correct answer. An XOR gate is designed to produce an output when its two inputs are different. If one input is high and the other is low, or vice versa, the XOR gate will produce a high output (1). If the inputs are the same (both high or both low), the XOR gate will produce a low output (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.
