WebApr 5, 2024 · Therefore, current through 12 Ω resistor = 0.67 A. 12. How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line? Suppose n resistors of 176 Ω are connected in parallel. 1/R = 1/176 + 1/176 + ……….n times 1/R = n/176 or R= 176/n Ω By Ohm’s law R=V/I 176/n = 220/5 n= (176 x 5)/220 = 4 13.
How many 176 ohm resistors (in parallel) are required to carry 5 A …
Web1 R = x× 1 (176) 1 R = x × 1 ( 176) R = 176 x 176 x. Now, as per Ohm’s Law, we get, V I = 176 x V I = 176 x. ⇒ x = 176×5 220 = 4 x = 176 × 5 220 = 4. Hence, in order to draw the required amount of current, four 176 Ω resistors will be needed. Related Questions: WebMar 21, 2024 · The continued fraction (="Euclidean"?) gives contfrac(x) = [0, 1, 5] so we have x = 1 / (1 + 1 / 5) and thus x = r 5r and we need 6 resistors, which is not optimal. A better configuration is by 5 / 6 = 1 / 2 + 1 / 3 = 2r ⊕ 3r so we need 5 resistors. dutch bike seat covers
