The colour of light emitted by an LED
depends on its band - gap energy

Depends on forward biasing
Depends on intensity of light falling on it
What is forward bias
When the cathode is more positive than the anode
When the anode is more positive than the cathode
When the resistor is more negative than current
When current changes at a higher rate than voltage
What is the function of a diode?
To block electricity
To produce sound
To make sure current flows in one direction
To make sure voltage flows in one direction
What happens if the diode is in reverse-biased mode?
Current can flow
Current cannot flow

Voltage cannot flow
Zener diodes are mostly used for
rectifier circuits
Filter Circuits
solar cells
Voltage regulator circuits
Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of
diode
semiconductor
conductor
insulator
superconductor
In the forward bias arrangement of a p-n junction diode,
the n-end is connected to the positive terminal of the battery
the p-end is connected to the positive terminal of the battery
the direction of current is from n-end to p-end in the diode
the p-end is connected to the negative terminal of the battery
which statement is correct? (the dark circles represent the electrons)
p-type of the diode is connected to the negative terminal.
Electron moves across the p-n junction, makes the diode forward biased
current will not flow in the circuit
reverse biased circuit
Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of
diode
semiconductor
conductor
insulator
superconductor
led works only in ______ bias
Forward
Reverse
