What's the difference between 040206030805 package in resistor and capacitor?
The relationship between package size and power is as follows
0201 1/20W
0402 1/16W
0603 1/10W
0805 1/8W
1206 1/4W
Correspondence between package size and package
0402=1.0mmx0.5mm
0603=1.6mmx0.8mm
0805=2.0mmx1.2mm
1206=3.2mmx1.6mm
1210=3.2mmx2.5mm
1812=4.5mmx3.2mm
2225=5.6mmx6.5mm
What is the difference between 1K 5% 0603 resistor and 0805 resistor
Ohm's law
The reciprocal of the total resistance is the sum of the reciprocal of the partial resistances
When are 0402 0603 0805 resistors and capacitors used
When using these resistors and capacitors, the most important consideration is the volume. Too large volume is not conducive to the high integration of products. For example, mobile phones are almost all packaged in 0402. If you want to use 0603 or 0805, you will become mobile phones
Does the current and voltage change when the resistance is shunted through the consumer
Well, do you know u = IR?
I don't know what you mean by the questions. Can you be more detailed?
How to calculate the current and voltage of resistance in parallel circuit? Everyone knows the calculation method of resistance. How can the current and voltage of resistance in shunt calculate 0.0 efficiency
Don't plagiarize. I've seen the others. No
First come, first served. I know I'll add 10 points in the future!
If the voltages at both ends of a parallel circuit are equal, the shunt current is equal to the voltage divided by the shunt resistance
In parallel circuit, when the resistance of one branch decreases, what are the changes of current and voltage of other users? What are the changes of current and voltage of main circuit?
There is a voltmeter connected in parallel with all electrical appliances. After the above situation, what changes does the voltmeter have?
The resistance of one branch decreases, that is to say, the current of this branch will increase, but the voltage at both ends of the parallel circuit will not change with the resistance of one branch. It can not affect the current and voltage of the other branch, but it can affect the current of the trunk, because the current of the trunk is the sum of the currents of each branch, So a branch of the current increases, the total current value will also increase, as long as the power supply is enough, the voltage will not change, here we all think that the power supply is enough, that is to say, the voltage will not change! With a voltmeter and all electrical appliances in parallel, after the above situation, the voltmeter does not change!
There is an electrical appliance in the circuit, the voltage at both ends is 6V, the current passing through is 200mA, what is the work of the current in 5min
How to find the formula
Work of current w = Qu = uit
I=200mA=0.2A,t=5min=300s
W=6V*0.2A*300s=360J
There is an electrical appliance in the circuit. The voltage at both ends is 6V, and the current is 200mA. What is the work done by the current in 5min?
Known: u = 6V, I = 200mA = 0.2A, t = 5min = 300s? W = uit = 6V × 0.2A × 300s = 360j
A 4 Ω resistor is connected in series with a consumer at both ends of the 6V power supply. Now we only know that the actual power of the consumer is 2W. How much current may pass through the consumer?
Let the current through the consumer be I, ∵ ur = IR = I × 4 Ω, u = pi = 2WI, ∵ u = ur + U = I × 4 Ω + 2WI, which is reduced to 2i2-3i + 1 = 0, ∵ I = 1A or I = 0.5A. A: the current through the consumer may be 1A or 0.5A
The thinner wire is thicker, the resistance is smaller, the voltage shared by the transmission line is smaller, and the voltage of the home circuit is larger, so the light bulb in the farmer's home is on
I don't understand that if the resistance is small, how can the voltage shared by the transmission line become smaller? Does it mean that the resistance is small, but the voltage is large? Why is the voltage of the home circuit larger?
