What is the outcome of high resistance in an electrical circuit?

High resistance in an electrical circuit leads to decreased current flow due to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I = V/R. When resistance increases while the voltage remains constant, the current must decrease. This is fundamental to understanding how electrical circuits operate: higher resistance restricts the flow of charge carriers, leading to a lower current.

In circuits, if you have a high resistance component, it will impede the movement of electrons, which are responsible for the current. This results in less current being available in the circuit to perform work, such as powering a device. Consequently, in practical applications, components with high resistance can lead to reduced performance or slow operation of electrical devices.

In summary, high resistance directly correlates with a drop in the amount of current flowing through the circuit.
