Second study English with Electronic components
Electronics Learning
This is a second study English that my son use learn it by the electronic components. Today we will know three words below. 1. Different Q: Is the resistors different the capacitor? A: Yes, the resistor is different the capacitor. 2. Similar to Q: Are the two transistors similar? A: Yes, the transistors are similar. Q: Is 2SC458 similar to 2SC1815? A: Yes, 2SC458 is similar to 2SC1815. 3. The same (as) Q: Is LDR the same as photoresistor? A: Yes,the LDR is the same as the photoresistor. I hope my son’s learning will be useful for you.
How to make a simple series circuit
Electronics Learning
Today, my son experiment on the simple series circuit. To understand current flow and voltage across all devices in circuit. Parts he will needs 1. R2____1K 0.25 watts resistors 2. R1____100 ohms 0.25 watts resistors 3. the power supply 4. the breadboard 6. the digital multimeters 7. Wire jumpers How to experiment First of all, he builds the simple series circuit by use one resistors as Figure 1. He installed all resistors into the breadboard. Then, apply the 10V power supply to the resistor as complete circuit. Figure 1 the simple electronic circuit Then, he measure a current of the …
