Current is coulombs per second). Resistance (measured with ohms) restricts the flow of charge (conductors have low resistivity, insulators are high. Resistance increases with length and decreases with crosd-sectional area) Ohm's law is V = IR (or, with current isolated, I = V / R) permalink fedilink source parent [–] A_Very_Big_Fan@lemmy.world 9 points 5 months ago How so? permalink fedilink source parent
