参考电路图:
常规电路图及分析电路图以下以分析电路图示意计算公式:
I1=(VCC1-VCC2)/(R3+R2)
UOC=VCC2+I1*R3
RO=R2*R3/(R2+R3)
I2=UOC/(RO+R1)
UR1=I2*R1
以下将示例电路带入参数演示计算:
例电路带入参数演示计算I1=(VCC1-VCC2)/(R3+R2)
I1=(36V-3.3V)/(1.5K+6K)=4.36mA
UOC=VCC2+I1*R3
UOC=3.3V+4.36mA*1.5K=9.84V
RO=R2*R3/(R2+R3)
RO=6K*1.5K/(6K+1.5K)=1.2K
I2=UOC/(RO+R1)
I2=9.84V/(1.2K+1.5K)=3.64mA
UR1=I2*R1
UR1=3.64mA*1.5K=5.47V
