SUMMARY
The maximum voltage for a circuit with a 2.7 kOhm and a 3.8 kOhm resistor connected in parallel, which is then connected in series with a 1.5 kOhm resistor, is determined by the power rating of each resistor. Each resistor is rated at 0.9 W. To find the maximum voltage, first calculate the equivalent resistance of the parallel resistors and then the total resistance in series. The formulas used include \( V = I \times R_{eq} \) and \( I = \sqrt{\frac{P}{R}} \) for each resistor to ensure the power dissipation does not exceed 0.9 W.
