In the next two sections, we’ll cover the total resistance and conductance inparallel circuits. Total Resistance in a Parallel Circuit Examining the parallel resistance circuit of Figure 1, we should be able to see that multiple paths (branches) for current reduce the total resistance for the ...
Calculate the total resistance in a circuit with two resistors in parallel, where R1 = 100 ohms and R2 = 200 ohms.相关知识点: 试题来源: 解析 答案:\( R_{total} = \frac{R1 \times R2}{R1 + R2} = \frac{100 \times 200}{300} = \frac{20000}{300} = 66.67 \) ohms ...

wherein the resistance circuit making contact 2 and the resistance circuit breaking contact 3 connected in parallel, one end of the parallel circuit is connected to one end of a common resistor, the other end of the resistor and the other end of the parallel circuit respectively connected main...
∴ I = 5/25 ∴ I = 0.2A When resistors are connected in series, the current flowing in the circuit will be the same at every point in the circuit. Therefore, by using Ohm’s law, V2 = IR2 ∴ V2 = 0.2 x 15 = 3V Therefore, the potential difference across the 15 Ohms resistor ...
