Looks good, your turn

Oops, I forgot to specify you could use NOT too. Looks right, your turn!wec01 wrote:UTF-8 U+6211 U+662F wrote:Simplify the following logical expression in terms of only AND and OR: XOR(A, XOR(B, AND(NOT(OR(A, B)), NOT(XOR(B, NOT(AND(A, A)))))))OR(AND(NOT(A), B), AND(B, NOT(A)))

Suppose you find an LED whose datasheet contains the above graph. What value resistor should you put in series with this LED and a 5V power source in order to have a current of 20 mA going through the circuit.
Is it 175 ohms?

Not quite, but I see what you did:krasabnk wrote:wec01 wrote:

The voltage values on the graph give the voltage drop across the LED; you need to calculate the voltage drop across the resistor before you can use Ohm's law to find it's value.

Oh, so is it 75 ohms?

Think variables and complements
