What is the sensitivity of a voltmeter using 0-5mA meter movement?
S = 1/ Ifsd = 1/5mA = 200 Ohm / V
What is a meter stop?
A meter stop is a small metal or plastic peg placed just beyond the limits of normal meter movement on an analog meter movement to prevent the needle from moving too far off scale. Overloading a meter so that it hits the meter stop hard is often called "pegging" the meter and can damage it by bending the needle.
Is a moving coil meter an analog or digital device?
A moving coil meter is an analog device. It operates using a coil suspended in a magnetic field, which moves in response to an electric current, causing the pointer to indicate a value on a scale. This continuous movement and the corresponding scale reading represent the measured quantity in an analog format, as opposed to discrete digital readings.
How much does a cube of concrete cost?
The cost of a cube of concrete, typically referred to as a cubic yard or cubic meter, varies based on factors such as location, quality, and supplier. On average, a cubic yard of concrete can range from $120 to $150, while a cubic meter may cost between $100 to $200. Additional expenses for delivery, additives, or special mixes can also affect the final price. It's best to check with local suppliers for precise pricing.
Why are moving iron test instruments not used with DC although they can work in DC?
For moving-iron instrument magnetic field is caused when the current (voltage) passes the fixed circle. When the current (voltage) passes the fixed circle，the two iron plates are magnetized ,rotational torque is resulted, the deflection angle indicate measured current. Because the magnetized polarity is same for AC or DC, moving-iron instrument can be used in AC and DC circuit. For permanent-magnet moving-coil instrument magnetic field is caused by the permanent-magnet, When the DC current passes the moving coil, rotational torque is resulted,so the deflection angle indicate measured DC current. As AC current passes the moving coil ,because inertia of moving parts of meter the deflection angle indicate rotational torque average, but rotational torque average is zero in cycle, moving parts of meter is´t deflec,so permanent-magnet moving-coil instrument only is used in DC circuit.
What are the factors affecting folk dances?
There are quite a few factors that affect folk dancing. These factors include rhythm, meter, and associated steps for dancing.
What are the Limitation of meter bridge?
Some limitations of a meter bridge include: Limited accuracy due to human error in taking measurements. Restricted use in measuring resistance values that are too high or too low. Sensitivity to external factors like temperature and vibrations, which can affect the readings. Inherent resistance in the connecting wires can introduce errors in the measurements.

Define sensitivity of meter?
sensitivity of a multimeter is defind as the smallest value that can be measured by the meter . some time it may also be given the recprocal of full scale defflection and resistance . volt/ohm.

What is the sensitivity of a meter stick?
That's a weird way to talk about a meter stick, but I'll take it seriously, play dumb, and discuss the meter stick just like any other piece of test equipment: When you select the device you need for the measurement you're about to perform, you have to consider its sensitivity ... the size of the smallest measurement it can detect and indicate for you with reasonable accuracy. A meter stick usually has all 100 centimeters marked on it, and millimeters marked for the first one or two centimeters. So I would say that by handling, moving, and flipping the stick appropriately and cleverly, you could perform reasonably accurate measurements in the range of 1/2 millimeter to 1 meter ... 2,000 to 1 with a wooden stick, which is not too shabby !

What is the cost associated with moving a gas meter to a new location?
The cost of moving a gas meter to a new location can vary depending on factors such as the distance of the move, the complexity of the installation, and any additional work required. Typically, the cost can range from a few hundred to a few thousand dollars. It is recommended to contact your gas provider for an accurate estimate.
What are the types of electrodynamometer?
The two main types of electrodynamometer are attracted disc type and moving coil type. In the attracted disc type, two stationary coils create a magnetic field that attracts a disc attached to the moving coil. In the moving coil type, the coil is suspended between stationary magnets and experiences a force when current flows through it.
Scale used in moving coil meter is?
Linear Scale
