AC AND DC MEASURING INSTRUMENTS - Practice Mode

1) Which parameter is measured by a multimeter?

Voltage Energy Frequency Time duration

Correct Answer: Voltage

Explanation:

A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter (VOM).

2) Which torque is used in PMMC meter movement?

Low torque High torque Moderate torque Insufficient torque

Correct Answer: Moderate torque

Explanation:

Moderate torque is used in PMMC meter movement.

3) Which instrument used to measure resistance, capacitance and inductance?

LCR bridge Wein bridge Kelvin bridge Wheatstone bridge

Correct Answer: LCR bridge

Explanation:

LCR instrument is used to measure resistance, capacitance and inductance.

4) Find the value of shunt resistance required for 1 mA meter to extend the range and measure 10 mA (RM = 27 Ohm) ?

1 Ohm 2 Ohms 3 Ohms 4 Ohms

Correct Answer: 3 Ohms

5) In which arrangement the high value of resistor is connected to extend the range of voltmeter?

Star Delta Series Parallel

Correct Answer: Series

Explanation:

The range of voltmeter can be increased by connecting a suitable high resistors in series with it.
