In a combinational circuit, the output at any time depends only on the current inputs at that time.

Explanation

Combinational circuits are designed such that their outputs are determined solely by the present state of the inputs, without any consideration for past inputs or states. This means that the circuit performs a specific function based on the combination of inputs given at a particular moment. Unlike sequential circuits, which rely on previous states and have memory elements (like flip-flops), combinational logic circuits are transient and reactive in nature.

Examples of combinational circuits include adders, multiplexers, and encoders, where the results are calculated based purely on the current values of the input signals. Therefore, the relationship between inputs and outputs in combinations circuits is often represented by truth tables or logical expressions that change instantaneously with variations in the input signals. This property makes combinational circuits fundamental in digital electronics and logic design.
