WebThe long, thin wire shown in Figure 22–39 is in a region of constant magnetic field r B. The wire carries a current of 6.2 A and is oriented at an angle of 7.5° to the direction of the magnetic field. (a) If the magnetic force exerted on this wire per meter is 0.033 N, what is the magnitude of the magnetic field? (b) At what angle will WebCurrent measures the flow of charges through an area over time.

WebSep 12, 2024 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ, and resistivity is the reciprocal of electrical conductivity: ρ = 1 σ. The unit of resistivity in SI units is the ohm-meter (Ω ⋅ m. WebYou have been given a long length of wire. You measure the resistance of the wire, and find it to be R l o n g. You then cut the wire into n identical pieces (Figure 1) . If you connect the n pieces in parallel as shown (Figure 2) , what is the total resistance R t o t a l of the n wires connected in parallel? Express your answer in terms of R ... iris barth ahorn
