Hello all steemians. Hope you always be enjoy and have good days. On this occasion i want to share to you about How To Measuring Current And Voltage.
After learn this lesson, we hope be able to :
- Measure, read electric current in an ammeter and the make a circuit series
- Measure, read electric voltage in a voltmeter and the make a circuit parallel
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). Source
1. An Ammeter
An ammeter is :
An instrument used to measure current passing through a branch point or another part of a network.
An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Source
The unit of current is Ampere ( A )
The picture 1. of an ammeter and how to read electric current
An ammeter to measure current is always connected in Series in a circuit
2. Voltmeter
What is the voltmeter ?
An instrument used to measure the voltage across a load in a circuit.
A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. Source
The unit of voltage is Volt ( V )
The picture 2. a Voltmeter and how to read electric Voltage
What are he relation between ammeter and voltmeter
Conclusion
- The current can be measured with an ammeter
- An ammeter is always connected in series in a circuit
- The Voltage can be measured with a voltmeter
- A voltmeter is always connected in parallel in circuit
