You construct a circuit containing some component C, along with other circuit elements. You want to simultaneously measure the c
urrent through C and the voltage across C while it remains connected to the rest of the circuit. Indicate where you would connect an ammeter (A) and a voltmeter (V) to perform these measurements. Fill any remaining gaps with wires as needed to complete the connection with the rest of the circuit.
1 answer:
Answer:
The position of the ammeter is in series down the component. While the voltmeter must be connected in parallel. Its position is the gap through the component C.
The positions of one or the other are indicated in the image.
Explanation:
An ammeter is defined as a device used to measure current. Its unit is the ampere. While a voltmeter is used in the measurement of the potential difference between two points. Its unit is the volt. The ammeter must be connected in series with the point at which the current is to be measured, while the voltmeter must be connected in parallel.

Explanation:
Polyatomic ions are ions that contain more than one atom in each one of the ions.
Ionic compounds are made of cations (positive ions) and anions (negative ion). By convention, the cation is written before the anion.
List the ions in each compound:
<h3>CaCO₃</h3>Cation: ,
Anion: .
is a monatomic ion for it contains only one atom in each ion.
is a polyatomic ion for it contains four atoms (one C atom and three O atoms) in each ion.
