Thank you for correcting I will edit this, I want to write this actually. So, I don't know the second one is a semicircle or not. If that is I did correct. I don't have a question actually, mine is a confirmation.etotheipi said:
It's not drawn very well, but if they don't say otherwise, it looks close enough to a semicircle to consider it one, IMO.requied said:
thank you I had also thought soberkeman said:
I think the "25mm" is the radius of the wire itself, not the radius of the semicircle portion of the wire form. Yeah, that confused me pretty well also.kuruman said:

To calculate the resistance of a wire shape, you need to know three things: the resistivity of the material, the length of the wire, and the cross-sectional area of the wire. The formula for resistance is R = (ρ * L) / A, where ρ is the resistivity, L is the length, and A is the cross-sectional area.
The unit of measurement for resistance is ohms (Ω). This unit is named after the German physicist Georg Ohm, who first discovered the relationship between voltage, current, and resistance.
Yes, the resistance of a wire shape can change depending on the material, length, and cross-sectional area. For example, a longer wire will have a higher resistance than a shorter wire, and a thicker wire will have a lower resistance than a thinner wire.
Temperature can affect the resistance of a wire shape because it can change the resistivity of the material. In general, as the temperature increases, the resistivity of most materials also increases, resulting in a higher resistance.
Calculating the resistance of a wire shape is important because it helps us understand how electricity flows through different materials. It also allows us to design and build circuits that have the desired amount of resistance for proper functioning.
