How is adding a ammeter to a circuit different from adding a light bulb?
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit. ...
Can a multimeter be used as substitute of ammeter and voltmeter why?
yes it can read both ac and dc voltage and current . Answer The whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter! ...
The function and use of an ammeter and a voltmeter?
A: ACTUALLY they are both the same just the application makes one or the other. Their function is to measure potential difference on a load or circuitry ...

How is an ammeter converted to a voltmeter?
An ammeter can be converted into a voltmeter by connecting a resistor in series with it. This works best if the ammeter is a very sensitive ammeter, such as in the micro ampere range. More commonly, a voltmeter (or sensitive ammeter) is converted into an ammeter by placing a small resistor in parallel with it. ...
Why is an ammeter connected in series?
Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel. ...
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...
How is ammeter different from voltmeter?
A: There is no difference. Both read voltage. The interpretation is however is difference. The real significance is AC ammeter they read current as flux input. Even an ohmmeter is reads voltage to determine resistance as a function of IR drop ...
