The correct answer is: D. Oppose sudden changes in voltage.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors are used to reduce current flow, to divide voltages, to create biasing, to terminate transmission lines, and to adjust the values of other components.
Resistors can be made of various materials, including carbon, metal, and semiconductor. The resistance of a resistor is measured in ohms (Ω). The higher the resistance, the more the resistor opposes the flow of current.
Resistors are often used in circuits to control the flow of current. For example, a resistor can be used to create a voltage divider, which is a circuit that divides an input voltage into two or more output voltages.
Resistors can also be used to create biasing circuits, which are circuits that provide a stable voltage reference for other components in a circuit.
Resistors are an essential component in many electronic circuits. They are used to control the flow of current, to divide voltages, to create biasing, to terminate transmission lines, and to adjust the values of other components.
Here is a brief explanation of each option:
- A. Can dissipate considerable amount of power. This is true for all electrical components, not just resistors.
- B. Can act as energy storage devices. This is true for capacitors and inductors, not just resistors.
- C. Connecting them in parallel increases the total value. This is true for capacitors and inductors, not just resistors.
- D. Oppose sudden changes in voltage. This is true for resistors, but not for capacitors and inductors.
