WebThe amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm. Using Ohms Law, this gives us a flow (current) of 1 amp. Using this analogy, let's now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher. WebJul 12, 2024 · For instance, a series circuit has the following resistors: a 6 Ω, a 5 Ω, and an 8 Ω resistor. The total resistance in a series circuit is given by R1 + R2 + R3. R = 6 + 5 + 8. R = 19 Ω. If you are not given the individual resistance values, you can use Ohm’s law and calculate the resistance using the formula: V = IR.
