How is current measured?
1 Answer
Current is measured using an instrument called an ammeter or current meter. The unit of measurement for electric current is the ampere, which is represented by the symbol "A." An ammeter is designed to measure the flow of electric charge through a circuit.
There are two main methods for measuring current:
Series Connection: In this method, the ammeter is connected in series with the circuit component or the section of the circuit where you want to measure the current. It becomes a part of the current path, and all the current flowing through that section of the circuit will pass through the ammeter. This method is commonly used for direct current (DC) circuits.
Clamp-On Ammeter: For measuring alternating current (AC) in a conductor without breaking the circuit, a clamp-on ammeter is used. It has a split-core design that allows it to be opened and clamped around the conductor without the need for direct electrical contact.
To obtain an accurate current measurement, ensure that the ammeter's range (current capacity) is set appropriately. If the measured current exceeds the ammeter's range, it may damage the instrument and provide incorrect readings.
Keep in mind that electrical measurements can be hazardous if not performed with care. Always follow safety precautions and, if you are unsure or inexperienced, consider consulting a qualified electrician or technician to handle the measurements.
