What is the current through this circuit?

What is the total resistance of this circuit?

What is the equivalent resistance of this circuit?

If you connect a wire from the 5V of your Arduino to an LED (2.0 V drop LED) and connect the other end of the LED to a 200 Ohm resistor and then connect the other end of the resistor to the Arduino’s ground, what is the current through the LED?

If you connect a wire from the 5V of your Arduino to an LED (2.0 V drop LED) and connect the other end of the LED to a 200 Ohm resistor and then connect the other end of the resistor to the Arduino’s ground, What is the current through the resistor?

Which direction does the current flow?

If you connect a wire from the 5V of your Arduino to an LED (2.0 V drop LED) and connect the other end of the LED to a 200 Ohm resistor and then connect the other end of the resistor to the Arduino’s ground, If you put the resistor in the other way (flip which pin is connected to the LED and the Arduino) what happens?
