Problem B Resistor Rc represents the coil resistance of a certain DC motor. Rc Vc Vbb represents the logic high output of a digital system that is powered with 3.3V. ( 3.3V represents a logic high and OV represents a logic low) When the digital system outputs a logic high, the full 12V supply needs to be across the motor (meaning that the collector-emitter should act like an ideal closed switch.) Q1 Design a value for resistor Rb that just meets the design requirement.

Question

determine Rb.  show the formula and how you got the answer 

Problem B Resistor Rc represents the coil resistance of a certain DC motor. Rc Vcc Vbb represents the logic high output of a digital system that is powered with 3.3V. ( 3.3V represents a logic high and OV represents a logic low) When the digital system outputs a logic high, the full 12V supply needs to be across the motor (meaning that the collector-emitter should act like an ideal closed switch.) Q1 Design a value for resistor Rb that just meets the design requirement. Vc Rc beta 3.3V 12V 250 90
