Resistors in series and in parallel can change the total resistance in a circuit. What is Resistance in series and parallel? Resistors in series and in parallel change the total resistance in a circuit. Special components called resistors are made especially for creating a precise quantity of resistance in a circuit. They are generally made of metal wire or carbon and constructed to maintain a stable steady amount of resistance over a wide range of environmental conditions. Resistance in series and parallel equation To calculate Resistance in series we use this equation. $R_t = {\mathit R_1 \text + \mathit R_2}$ Resistance in series and parallel demo In this tutorial you will learn how to calculate the total resistance of resistors in series and parallel. Chilled practice question Calculate the current in a circuit if it is supplied with a voltage of 36 V and has two resistors in series one 6 Ω and the other 3 Ω. Frozen practice question Three resistors are connected in parallel, resistor A is 2 Ω , resistor B is 4 Ω, and resistor C is 5 Ω . What is the total resistance in the circuit ? Science in context Resistance in series and…
