Question

which volt amp curve represents a cv output?

Explanation:

Define constant voltage characteristics

Using the Constant Voltage knowledge point
A constant voltage (CV) power source maintains a relatively stable, flat voltage output across a wide range of amperage changes. On a volt-ampere curve, this is represented by a nearly horizontal line with a very shallow downward slope.

Define constant current characteristics

Using the Constant Current knowledge point
A constant current (CC) power source produces a steep, drooping curve where amperage remains relatively stable despite significant fluctuations in voltage.

Compare the given curves

Using the Constant Voltage and Constant Current knowledge points

• Curve A shows nearly horizontal, flat lines where voltage changes very little as amperage increases. This represents a CV output.
• Curve B shows steep, drooping curves where voltage drops sharply as amperage changes. This represents a CC output.

Answer:

• (A) (Correct answer)
• (B)
