• Increases

• Decreases

• Remains the same

• Becomes zero

In a parallel resistor circuit, the total resistance is always

• Greater than the smallest resistor

• Equal to the smallest resistor

• Less than the smallest resistor

• Equal to the sum of the resistors

Ohm's law states that the current through a resistor is proportional to?

An LED operates in which type of bias?

• Forward bias

• Reverse bias

• Zero bias

• Both forward and reverse bias

What happens if the current through an LED exceeds its maximum rating?
