Authoritative PPT Summary
"Measurement of Current" Current and Circuit PPT Courseware 7
Experiment 1 How to make a small light bulb light up?
Connect the dry cell battery, small light bulb, and switch with wires.
Note: When connected, the switch status is disconnected!
Free electrons move in the opposite direction to the current.
Experiment 2 Compares the lighting conditions of small light bulbs when using one dry battery and two dry batteries as power sources.
The power supply in the two circuits is different
The amount of electrical energy provided is different
The magnitude of the current in the circuit is different.
The greater the current flowing through the bulb, the brighter the bulb becomes.
2. The size of the current - current intensity (referred to as current)
1. Symbol: I
2. Unit:
(1) International unit: ampere → A (referred to as "amp")
(2) Commonly used units: milliamp → mA
Microamp →µA
(3) Unit conversion relationship:
1 A = 1000 mA 1 mA = 1000 microA
1Ａ=103mA 1mA=103 µA
Ammeter reading steps:
Step 1: Determine the measuring range
Step 2: Read the big box first
Step 3: Read the small grid again
How to measure the current through a circuit with an ammeter?
If the ammeter is used improperly, it is easy to burn out.
What should you pay attention to when using it?
Reading: P22, Correct use of ammeter
Correct use of ammeter
1. Choose the measuring range correctly.
2. The ammeter must be connected in series in the circuit under test
3. Make the current flow in from the positive terminal of the ammeter and flow out from the negative terminal.
4. It is absolutely not allowed to connect the ammeter directly to the two poles of the power supply without using electrical appliances, otherwise the ammeter will be burned.
What should I do if the measured current cannot be estimated in advance?
Use the maximum range first and test it quickly.
If the pointer deflection is too small, use a smaller range.
If the pointer deflects beyond the range, switch to an ammeter with a larger range.
