Description
"Measurement of Current" Current and Circuit PPT Courseware 9
current
1. Current intensity: indicates the size of the current
Current intensity Abbreviation Current Symbol I
2. The basic unit of electric current: Ampere, abbreviated as A, symbol A
Commonly used units: milliampere (mA) and microampere (μA)
Conversion relationship: 1A=1000mA 1mA=1000 μA
Introduction to physicists
Ampere was a French physicist who had read extensively since childhood and had an amazing memory and extraordinary mathematical talents. In September 1820, he conducted in-depth research on the interaction between electric currents and achieved fruitful results in a short period of time.
2. Connection of ammeter:
(1) The ammeter must be connected in series with the electrical appliance being measured.
(2) Current must flow in from the positive terminal and flow out from the negative terminal.
(3) The measuring range must be selected correctly.
(4) It is not allowed to connect the ammeter directly to the two poles of the power supply!
Rules for using ammeter
The ammeter should be connected in series in the circuit
Current flows into the ammeter from the "+" terminal and out from the "-" terminal.
The magnitude of the current being measured cannot exceed the range of the ammeter.
Do not connect the ammeter directly to the poles of the power supply.
3. Reading of ammeter:
(1) Clarify the range of the selected ammeter;
(2) Determine the graduation value of the ammeter;
(3) Read the number from the pointer position.
practice
1. Connect the physical diagram. It is required that two lamps be connected in parallel. The switch controls the two lamps. The ammeter measures the current of lamp L2 (about 0.5 A) and draws the circuit diagram.
2. Connect the physical diagram according to the given circuit diagram.
3. The switch controls __________, ammeter A1 measures the current of __________, and ammeter A2 measures the current of __________. Then draw the circuit diagram.
