Equation for finding current
WebSep 12, 2024 · First, we calculate the current density: J = I A = 10 × 10 − 3A 3.31 × 10 − 6m2 = 3.02 × 103 A m2. The resistance of the wire is R = ρL A = (1.68 × 10 − 8Ω ⋅ m) 5.00m 3.31 × 10 − 6m2 = 0.025Ω. Finally, we can find the electrical field: E = ρJ = 1.68 × 10 − 8Ω ⋅ m(3.02 × 103 A m2) = 5.07 × 10 − 5V m. Significance WebJul 5, 2024 · The ideal diode equation is very useful as a formula for current as a function of voltage. However, at times the inverse relation may be more useful; if the ideal diode …

WebSep 12, 2024 · From the right-hand rule, the magnetic field d→B at P, produced by the current element Id→l is directed at an angle θ above the y -axis as shown. Since d→l is parallel along the x -axis and ˆr is in the yz -plane, the two vectors are perpendicular, so we have dB = μ0 4π Idlsinπ / 2 r2 = μ0 4π Idl y2 + R2 where we have used r2 = y2 + R2. WebFor any quadratic equation: ax^2 + bx + c = 0 ax2+bx+c=0, the quadratic formula gives us the roots (the zero-crossings): x=\dfrac {-b \pm\sqrt {b^2-4ac}} {2a} x=2a−b± b2−4ac Looking back at the characteristic equation, …
Web6 years ago. Here's one path to an answer. I'll start with the basic capacitor equation: q = Cv. (q = charge, C = capacitance, v = voltage) Now convert the variables to unit names.
