This circuit shows a switch connected to a buffer, then an LED tied to ground. The intention of the circuit is to turn on the LED when the switch is closed. This circuit has a problem. What is it
Choice 1 of 8: LED orientation is wrong
Choice 2 of 8: Buffer is in the wrong position
Choice 3 of 8: Input to the buffer needs a resistor with a value greater than the buffer's input resistance tied to ground
Choice 4 of 8: Input to the buffer needs a resistor with a value less than the buffer's input resistance tied to ground
Choice 5 of 8: Output to the buffer needs a resistor with a value greater than the buffer's output resistance tied to ground
Choice 6 of 8: Output to the buffer needs a resistor with a value less than the buffer's output resistance tied to ground
Choice 7 of 8: Input to the buffer needs a resistor with a value greater than the buffer's input resistance tied to Vcc
Choice 8 of 8: Input to the buffer needs a resistor with a value less than the buffer's input resistance tied to Vcc
