principles of measurement of dc current and ac voltage
Dear,
Electrical voltage and current are two important quantities in an electrical network. The voltage is the effort variable without which no current is available. It is measured across an electrical circuit element or branch of a circuit. The device that measures the voltage is the voltmeter.
To measure Current :
1. Turn the knob to the DCV section.
2. Choose the current rating. The display will show current in both rating.
3. Connect the testing leads to the set up.
4. Turn ON the multimeter.
5. Note down the reading.
To measure voltage:
A 9V DC supply is given to power the circuit. The LED glows as soon as the connection is made. Make sure the wires are tightly secured.
1. Then connect the testing leads to the multimeter.
2. Turn the knob to the DV voltage section (because you are measuring Direct voltage).
3. Connect the probes as per polarity.
4. Power on the multimeter.
5. Note down the reading.
hope it Helps!
