What occurs when a circuit has too much resistance relative to the applied voltage?

When a circuit has too much resistance relative to the applied voltage, the current that flows through the circuit decreases. This relationship is based on Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). Thus, if the resistance increases while the applied voltage remains constant, the overall current will decrease.

This decrease in current can lead to noticeable effects in the circuit, such as insufficient power to drive connected devices. It also implies that other elements of the circuit may not function properly due to the low current flow.

In contrast, the other outcomes listed do not accurately represent the situation described. A short circuit typically occurs with low resistance paths, causing excessive current; voltage increase is not a consequence of high resistance; and while power loss can occur in a high-resistance scenario, it is not a direct result of resistance alone, particularly in the context of the relationship between voltage and current. Thus, the significant relationship is that increased resistance leads to decreased current flow.
