4 cards from this section. Quick, good the night before a test.
Define a diode and its primary function in a circuit.
Think about its role in controlling current flow.
Explain KCL in your own words.
Recall the flow of water in pipes.
What does a diode do in a circuit?
Think about what happens when you connect a battery.
True or False: KVL states that the total voltage around any closed loop must equal zero.
Recall how energy is conserved in a circuit loop.
A diode with a threshold voltage of 0.7 V is applied in a circuit with a 5 V supply and a series resistor of 1 kΩ. Calculate the current through the diode when it conducts.
Start by calculating the voltage drop across the resistor.
Evaluate KCL at a junction with three current paths of 2 mA, 3 mA, and an unknown current. What is the unknown current?
Consider all currents entering and leaving the junction.
