Homework Equations
The Attempt at a Solution
I needed some practice, and I want to ensure I understand for the harder problems later.
(a) The diode is going to behave like a short circuit, so the current can be found from ##I = \frac{5V - (-5V)}{10k} = 1 mA##. The voltage will be entirely across the ##10k## resistor, and so ##V = 0 V##.
(b) The diode is going to behave like an open circuit, hence the current in the branch is ##I = 0 A##. None of the voltage will be across the resistor since there is no current, and so ##V = 5V - (-5V) = 10V##.
(c) The diode is going to behave like a short circuit again, so the current can be found from ##I = \frac{5V - (-5V)}{10k} = 1 mA##. The voltage ##V## will be entirely across the resistor, so ##V = 5V - (-5V) = 10V##.
(d) The diode will behave as an open circuit, so ##I = 0 A##. The voltage is a bit confusing to me though, would it be ##10V## again? I'm finding it difficult to reason it out.
