What is the correct way to test a diode using a multimeter?

• Set the multimeter to the diode setting and observe the reading

• Connect the multimeter in parallel with the diode

• Use the AC voltage setting

• Measure the diode's resistance

How do you discharge a capacitor safely before testing it?

• By heating the capacitor

• By connecting a resistor across the terminals

• By freezing the capacitor

• By shorting the terminals with a wire

What does the hfe setting on a multimeter test?

• The current gain of a transistor
