A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.

A black and white scene showing men on horseback and men standing in a field. this print, created by picasso, displays a bold, highly contrasting design, which is characteristic of wood engraving.
Engraving begins by using a sharp, hand-held cutting device called a chisel to draw a design directly onto a metal plate. The tip of the chisel is sharp and pointed. The technique of wood engraving has been used for centuries to reproduce drawings and paintings.
This allowed more people to own or see the artwork of artists who would otherwise only have the original, eliminating the possibility of additional "copies" of their own images. By the 19th century, it was largely abandoned in favor of etching.
Picasso's use of chisels was always unorthodox, but he and other artists used chisels to create sharp, crisp lines on his plates that were etched into the printed image. converted evenly.
The correct answer is option B.
