In an electrical circuit, what does a higher resistance indicate?

A higher resistance in an electrical circuit is indicative of a reduction in current flow. According to Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R), the relationship can be expressed as I = V/R. This means that for a given voltage, if resistance increases, the current must decrease.

When resistance is high, it creates an obstacle for electrons to flow through the circuit, thus limiting the amount of current that can traverse it. This principle is crucial in circuit design and troubleshooting, as understanding the impact of resistance on current helps in ensuring the circuit operates within safe and intended parameters.
