Final answer:
To build a combination series-parallel resistive circuit using 220 kΩ resistors, you can connect them in either a series or parallel configuration. In a series circuit, the equivalent resistance is the sum of the individual resistances, while in a parallel circuit, the total resistance can be calculated using the reciprocal formula.
Step-by-step explanation:
To build a combination series-parallel resistive circuit using the large blue resistors (220 kΩ), you can connect the resistors in different configurations based on whether you want to create a series circuit or a parallel circuit. In a series circuit, the resistors are connected sequentially, and the same current passes through each resistor. The equivalent resistance in a series circuit is the sum of the resistances of all the individual resistors. For example, if you connect three resistors in series, each with a resistance of 220 kΩ, the equivalent resistance would be 660 kΩ (220 kΩ + 220 kΩ + 220 kΩ). In a parallel circuit, the resistors are connected in parallel branches, and the voltage across each resistor is the same. The total resistance in a parallel circuit can be calculated using the formula 1/Req = 1/R1 + 1/R2 + 1/R3, where Req is the equivalent resistance and R1, R2, and R3 are the resistances of the individual resistors. For example, if you connect three resistors in parallel, each with a resistance of 220 kΩ, the equivalent resistance would be approximately 73.33 kΩ.
