What are the difference between a multimeter and a voltmeter?

A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, a multimeter combines a voltmeter, an ammeter, and an ohmmeter. The two main kinds of a multimeter are analog and digital. A voltmeter measures the potential difference (voltage) between two points. the voltmeter only measures volts.


What is the difference between a volt meter and a am-meter?

A voltmeter measures the difference in potential between two points on a circuit. An ammeter measures the amount of current passing through a point in a circuit. Although you often see them packaged together in a tool called a multimeter, they measure different quantities: Voltage, also known as potential difference, measured in volts, and Current, measured in amperes, or just amps. Also, they're used in somewhat different ways: -- The voltmeter simply touches the two points in the circuit between which the voltage is measured. -- The ammeter has the circuit current flowing through it. That means the circuit must be broken briefly, and the ammeter connected into the 'hole', before the current can be measured. (There are instruments that are exceptions, but they're rather specialized. The statement above holds generally true for the common ammeter.)


Why is a voltmeter used rather than a potentiometer?

A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.


Does an ammeter measure current?

An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.


How is the reading on an ammeter be affected when one of the parallel resistors is removed?

decrease to half of its original value


What is the definition of a spam bridge?

I think you probably mean "bridge span" rather than "spam bridge." A bridge span is the part of the bridge between its supports.


If a condo building were to collapse what floor would be the safest to be on?

As a structural engineer, I would rather be on the second floor. Ask yourself this: Would I rather be under a bridge or on the bridge when it collapsed? The people in Michigan who rode the bridge down survived because the bridge did not fall as if dropped out of the sky. Part of the bridge "cushioned" the fall.


What materials is the Howrah bridge made of?

The Howrah bridge in India is made of steel and is riveted, rather than having nuts and bolts in its construction. It is a cantilever, floating bridge.


What is the function of Bypass diode in the test terminals of a pressure transmitter?

The function of the bypass diode is to allow the loop current to be measured without disconnecting the current loop connections. It therefore allows for a quick measurement of the loop current without disturbing any control or monitoring equipment that is connected to it. This is achieved by simply connecting an ammeter across the diode. If the voltage drop across the ammeter is less than that of the diode (about 0.6V) then all of the loop current will flow through the ammeter rather than the diode. The ammeter is therefore able to measure the loop current.


How fast would you fall if you jumped from a bridge?

It depends on height of the bridge. If you fall ten feet you don't have time to build up speed rather than if you were on a 100,000 foot bridge.


What are the typical reasons one might consider bridge financing?

Someone might consider bridge financing if they are looking to make a long term financing in the future. Bridge loans are usually very short term loans, so they might need cash rather quickly and intend to pay it off rather quickly so they would get a bridge loan.


The difference between an empirical distribution and a theoretical distribution?

Empirical Distribution: based on measurements that are actually taken on a variable. Theoretical Distribution: not constructed on measurements but rather by making assumptions and representing these assumptions mathematically.
