Webb20 feb. 2024 · The unit for resistance is an ohm and is given the symbol Ω (upper case Greek omega). Rearrranging I = V / R gives R = V / I, and so the units of resistance are 1 ohm = 1 volt per ampere: 1Ω = 1V A. Figure 20.2.1 shows the schematic for a simple circuit. A simple circuit has a single voltage source and a single resistor. WebbBackground information on Ohm’s law: Ohms law can be used to identify the relationship between voltage, current, and resistance in any DC electrical circuit discovered by a German physicist named, Georg Ohm. This law states that voltage is equal to the product of the total current and the total resistance. The equation for this law is often ...
