Question
Calculate the transformer turns ratio required to connect four parallel $16-\Omega$ speakers so that they appear as an $8-\mathrm{k} \Omega$ effective load.
Step 1
When resistors (or in this case, speakers) are connected in parallel, the total resistance (or impedance) can be calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ... In this case, all four speakers have a resistance of 16 ohms, so the formula Show more…
