# 250+ TOP MCQs on Advantages and Limitations of Maxwell Bridge and Answers

Electrical Measurements Questions and Answers for Campus interviews on “Advantages and Limitations of Maxwell Bridge”.

1. What is the significance of the balance equation on losses?
a) independent of losses in inductance
b) independent of losses in capacitance
c) independent of losses in resistance
d) independent of losses in the circuit
Clarification: The balance equation in a Maxwell inductance capacitance bridge is independent of the losses associated with an inductance. According to the balance equation the unknown inductance is computed as Lx = R2 R3 C1.

2. Balance equation is dependent on frequency.
a) True
b) False
Clarification: The balance equation in a Maxwell inductance capacitance bridge is independent on the measurement of frequency. The balance equation does not contain frequency terms such as ω and as a result, it is independent of frequency.

3. How can R1 be scaled?
a) by using a scale
b) by using an ohmmeter
c) by calibration
d) by using a galvanometer
Clarification: The resistance R1 in a Maxwell inductance capacitance bridge can be scaled through calibration. The value of the Quality factor Q can be read directly through calibration.

4. Scale of resistance can be calibrated.
a) True
b) False
Clarification: The resistance R1 in a Maxwell inductance capacitance bridge can be calibrated directly. As a result the value of the unknown inductance can be read directly.

5. Bridge can be used for the measurement of _________
a) high Q values
b) intermediate Q values
c) very low Q values
d) low Q values
Clarification: A Maxwell inductance capacitance bridge can be used for the measurement of low Q values only of the order of 1 to 10. This is because at high Q factor values the angular balance condition is not satisfied.

6. The balance condition is _________
a) is easy to obtain
b) is difficult to obtain
c) can’t be obtained
d) exists always
Clarification: The balance condition in a Maxwell inductance capacitance bridge is difficult to obtain. This occurs due to an interaction between resistance and reactance components in the bridge circuit.

7. Commercial Maxwell bridges measures _________
a) inductances in the range of 1 to 1000H
b) capacitances in the range of 10mF to 1F
c) resistances in the range of 0.001 Ω to 1Ω
d) power in the range of 1W to 50MF
