Its cross-sectional area is inversely proportional, i.e., in material and constant length, cross-sectional area is bigger, and resistance is smaller, also with the material of conductor
Resistivity has relationship, this rule is just the law of resistance) current-limiting resistance R112 and current-limiting resistance R213 are designed to can be by changing
Become the structure of length and width, thick its resistance value of size Control, its working principles are as follows:
It is assumed that the resistivity of lower reed material: ρ=3.2m Ω cm/mm2(1mm2The resistivity of material of sectional area 1cm length is
3.2m Ω), it is assumed that the electric current by lower reed is 10A.
The resistance value of R1 is calculated according to law of resistance formula R=ρ L/S such as icon dimensioning:
R1=ρ × L1/ (T1 × W1)=3.2m Ω × (3.5 ÷ 10) cm/ (0.2mm × 1.25mm)=4.48m Ω
If the width W121 (the width W224 of current-limiting resistance R2) of current-limiting resistance R1 is reduced to 0.8mm from 1.25mm,
(other parameters are constant) calculates the resistance value of R1 again:
R1=ρ × L1/ (T1 × W1)=3.2m Ω × (3.5 ÷ 10) cm/ (0.2mm × 0.8mm)=(resistance value subtracts 7m Ω
It is small)
Similarly change the thickness T122 (the thickness T225 of current-limiting resistance R2) of current-limiting resistance R1；Change the length of current-limiting resistance R1
It spends L123 (the length L226 of current-limiting resistance R2)
Electrical power calculation formula: P=UI；In pure resistor element circuit, according to Ohm's law U=IR；R=U/I；I=U/R generation
Entering in P=UI can also obtain: P=I2R=U2/R
Electrical power is when calculating R1=4.48m Ω: 112mW (milliwatt)；Electrical power is when R1=7m Ω: 175mW (milli
Watt)
