Final Answer:
A blank circuit has practically zero resistance.
Step-by-step explanation:
In electrical circuits, resistance is a property that opposes the flow of electric current. It is measured in ohms (Ω) and represents the ratio of voltage to current in a circuit. A blank circuit refers to a circuit that does not have any components or loads connected to it. In such a circuit, there are no resistors or other elements that impede the flow of current. Therefore, the resistance in a blank circuit is practically zero.
Resistance can be calculated using Ohm’s Law, which states that resistance (R) is equal to the voltage (V) across a component divided by the current (I) flowing through it:
R = V / I
In a blank circuit, there are no components to generate voltage or consume current. As a result, the voltage across the circuit is zero, and since dividing any value by zero is undefined, we cannot determine the resistance of a blank circuit using Ohm’s Law.
However, it is important to note that even though a blank circuit has practically zero resistance, it may still have some inherent resistance due to the conductive properties of the materials used for its construction. This inherent resistance can be considered negligible for most practical purposes.
To summarize, a blank circuit has practically zero resistance because it does not contain any components that impede the flow of electric current. However, it may still have some minimal inherent resistance.
