Does the ammeter read?

You are learning about: “Does the ammeter read?”. This is a “hot” question with 407,000 searches/month. Let’s fleetserviceshocrv.com learn more about Does the ammeter read? in this article.


The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.

Where would the ammeter have the same reading?

The ammeter would have the same reading if located between points d and e or between points f and a, as it does in the position shown. (Note that the script capital E stands for EMF, and r stands for the internal resistance of the source of potential difference.

What is an ammeter in series?

Ammeter in Series: An ammeter (A) is placed in series to measure current. All of the current in this circuit flows through the meter. The ammeter would have the same reading if located between points d and e or between points f and a, as it does in the position shown. (Note that the script capital E stands for EMF,…

What is the value of ammeter in real life?

That value of real world ammeters is usually VERY low like .01 to .1 Ohms which is essentially a short circuit and if placed across a source of power as shown, would normally m Impossible to calculate as there are too many unknowns and this is a very unlikely circuit to begin with.

Does an ammeter need to be connected to a voltage source?

They must not be connected to a voltage source — ammeters are designed to work under a minimal burden, (which refers to the voltage drop across the ammeter, typically a small fraction of a volt). Ammeter in Series: An ammeter (A) is placed in series to measure current.

5. What does it mean when an ammeter reads zero in a circuit?

Yes. Also zero resistance, in theory. A good ammeter will have a resistance measured in milliohms or less. This is similar to a short length of wire. An ammeter is passive and cannot have or produce volts. A small voltage can be read across an ammeter and is referred to as an insertion loss. Google Ohms Law for a better understanding of electrcity.
