In summary, at 1:00 pm, a 10 v potential difference is applied across a 50 ohm resistance, resulting in a current of 0.2 amps. This current is expected to remain constant after 5 minutes, regardless of the temperature.

At exactly 1:00 pm on a certain day a 10 v potential difference is suddenly applied across a 'real' resistence and generates a current of 0.2 amps in the resistence. The value of the resistence at this moment is about 50 ohms. Let's say the 10 v are held constant and current is allowed to travel through the resistence for 5 minutes. At the end of the 5 minutes, the current in the 'real' resistence is expected to be what? this is not a trick question, temp is not a factor.

Is temp constant?

What are you getting at? Is this a trick question or a genuine enquiry?
 

1. What is the resistance of a material?

The resistance of a material is a measure of how difficult it is for an electric current to pass through it. It is measured in Ohms (Ω) and is dependent on the material's composition, dimensions, and temperature.

2. How is resistance related to conductivity?

Resistance and conductivity are inversely related. This means that as resistance increases, conductivity decreases and vice versa. Materials with high conductivity have low resistance, allowing electricity to flow easily through them.

3. What factors affect the resistance of a material?

The resistance of a material is affected by its length, cross-sectional area, temperature, and type of material. Longer and thinner materials have higher resistance, while shorter and thicker materials have lower resistance. Temperature also plays a role, as most materials increase in resistance as their temperature increases.

4. How does resistance impact the flow of electricity?

Resistance acts as an obstacle to the flow of electricity. As the resistance of a material increases, so does the amount of energy needed for the current to pass through it. This results in a decrease in the flow of electricity, leading to a decrease in the amount of current.

5. Why is the value of resistance important in electrical circuits?

The value of resistance is crucial in determining the behavior of electrical circuits. It helps in calculating the amount of current and voltage in a circuit, as well as the power dissipated. It also plays a role in controlling the flow of electricity and preventing damage to components by limiting the amount of current that can pass through them.
