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. WebEverything in the circuit will remain the same. The current in the circuit and the voltage, everything will remain the same. So let's go ahead and do that. So what we'll do is I'll keep the rest of the circuit as it is. So let's draw the rest of the circuit as it is, but replace this combination with a single resistor of eight ohms. There it is.

"WebConsequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit. The "shunt" is nothing more than a resistor with a very low resistance. " - Example of high resistance in a circuit
