Does current change after crossing a resistor
WebOct 17, 2012 · - A the cross-sectional area. Using Ohm's law: V=RI Thus: V/R=nevA and so: v = (V/neAR)* (1/R) With the first terms in parentheses constant, the drift speed of electrons decreases as resistance increases (when a resistance is present). In other words, the electrons slow down in a resistor Please explain to me where my misconceptions lie. … WebJan 13, 2024 · So yes, the resistor restricts the current, but it does so over the entire loop. If the current leaving the resistor were lower than the current entering the resistor, that would mean that charge was …
