Question

Identify a situation in which you would want to have a high resistance and a situation in which youwould want to have a low resistance

Answer 1

In physics, high resistance is essential for safety in insulators, such as those for power lines, to prevent current leakage, while low resistance is desired in electrical wiring for devices to ensure minimal energy loss and efficient power transmission.

Step-by-step explanation:

In the realm of physics, scenarios necessitate the use of different resistance levels based on the desired outcome. A situation in which you would want to have a high resistance is an insulator for power lines. These ceramic insulators have resistances of 1012 ohms or more to prevent electrical currents from leaking away from the power lines. On the other hand, a situation where you would want a low resistance is in electrical wiring that powers devices. For example, a large-diameter copper wire which may have a resistance of 10-5 ohms, allowing electricity to flow with minimal energy loss.

Additionally, resistors control current flow in circuits; a huge increase in resistance will reduce current, while a huge decrease in resistance increases current flow. Considering safety, a person working around possible electric hazards would want high resistance insulation to protect against electrical injuries; a resistor shown with a resistance of 20 × 105 ohms is an example of a protective measure.

Answer 2

When you're being held hostage, you're going to want to have low resistance. Sure, it's not going to guarantee you'll live, however, it'll surely buy you time for support, think for a plan, and sadly delay your demise. High Resistance during workouts for better muscle. In contrast though, do you mean electrical resistance? That would be a different answer.
