Solar energy to electric energy
--- light and electricity
Middle, chemical energy
There are many paths. In nature, there are internal energy transformed into steam, potential energy transformed into water, and then transformed into electric energy
Solar energy conversion
What can be converted into first?
Conversion of light energy into electricity
How does solar energy turn into electricity
Simple principle: first of all, we need to understand what electric energy is. The so-called electric energy is the directional movement of charged particles. According to Einstein's photoelectric effect, light can make the electrons of some substances move, such as pure crystalline silicon. So solar panels are made of monocrystalline silicon, which is used to convert solar energy into electric energy
A motor, coil resistance 2 ohm, connect it to 220 V circuit, it can operate normally
If the motor consumes 4400w of power, what is the current through the coil? What is the electric power loss due to coil heating
Through coil current I = P / u = 4400w / 220V = 20A
Coil heating loss electric power P loss = I & # 178; r = (20a) &# 178; * 2 Ω = 800W
How to calculate the resistance of copper wire
What's the resistance of copper wire of 250m 6 square millimeter at 0? What's the resistance of copper wire of 250m 6 square millimeter at 30? How to calculate P in the formula is what's the meaning of each number of 0.00017? Is there a copper wire resistance meter? How to multiply the time and temperature
P is equal to 0.0165 * 10 ^ - 8. How can m be calculated
The relationship between copper wire resistivity and temperature is shown in the figure
According to the calculation relationship between resistivity and resistance, R0 = P * L / S = 0.0165 * 250 / 6 = 0.6875 ohm at 0 degree; R0 = P * L / S = 0.0165 * 250 / 6 = 0.6875 ohm at 30 degree
R30 = P * L / S = 0.0185 * 250 / 6 = 0.7708 Ω
 
What are the factors that affect the resistance? What is the impact?
A: the factors that affect the size of the resistance: material, length, cross-sectional area, temperature. (1) material: conductors of different materials, the resistance is generally different. (2) length: conductors of the same material and thickness, the longer the length, the greater the resistance; the shorter the length, the smaller the resistance; (3) cross-sectional area: conductors of the same material, the same
Why is Newton's IQ higher than Einstein's? (Newton's is 290, Einstein's is 278)
 
High is high. As for your question, I think Einstein's Science City is more difficult than Newton's, so if you ask like this, it only means that Einstein discovered and studied this theory, but Newton didn't study it, it doesn't mean that his IQ can't be studied. I hope it can help you
The coil resistance of a motor is 2 Ω. When it is connected to the 220 V power supply, the current through the motor is 10 A. calculate: (1) the electric power consumed by the motor; (2) the output power of the motor rotor; (3) the heat generated by the motor per minute; (4) the efficiency of the motor
(1) Electric power consumed by motor: P = UI = 220 × 10 = 2200W; (2) output power of motor rotor: P output = P − I2R = 2200-100 × 2 = 2000W; (3) heat generated on coil: q = i2rt = (10) 2 × 2 × 60s = 12000j; (4) efficiency of motor: η = P output: P = 20002200 × 100% = 90.9%. Answer: (1) electric power consumed by this motor is 2200W; (2) output power of motor rotor is 200 (3) the heat produced by the motor is 12000j per minute; (4) the efficiency of the motor is 90.9%
How to calculate the resistance of copper wire
We know the length, cross-sectional area and resistivity of copper wire. We also know the α value at 20 ℃. How to calculate the resistance of copper wire at 100 ℃
