design a "dummy" indicator light for your car. The cheapest bulb available is a #47 incandescent lamp, rated for 6.3 V at 150 mA. The problem is that your car battery generates 13.5 V when your car is. Select the appropriate resistor to add to the circuit in order to reduce the voltage across the bulb to the appropriate level. Choose the nearest 10-% resistor value and determine what its power rating should be. The lifespan of an incandescent lamp is inversely proportional to the voltage applied to it, so round accordingly. Hint: be sure to recalculate the actual operating current with your selected resistor before determining its required power rating. Draw the circuit.
