dall of the above​

Answer 1

Answer:

(b) Impedance triangle.....

Answer 2

Option a) Voltage triangle

Voltage triangles are used in series ac circuit.

• A right-angled triangle called a "power triangle" is used to demonstrate the relationship between apparent, reactive, and active power. True power, Active Power, or Real Power are all terms used to describe the power that is actually consumed or used in an AC circuit. It is measured in kilowatts (kW) or megawatts (MW).
• Current I is drawn before the voltage drop across the inductive reactance VL =IXL. In a pure inductive circuit, the current lags the voltage by an angle of 90 degrees.
• The applied voltage V is equal to the vector sum of the two voltage drops VR and VL.
• If two of the three power values are known, a power triangle can be used to determine the active, reactive, and apparent power in an AC circuit. Electrical loads can be combined in a variety of ways, such as pure resistive, inductive capacitive, or RL, RC, RLC, LC, etc.
