Question

If a Newtonian resistance wire has a current of 1.5A flowing through it, the potential difference between the two ends of the wire is 120V. Adjust the voltage to reduce 0.25 times the original voltage, calculate the amperage through the resistance conductor when adjusting the voltage?

Answer 1

Step-by-step explanation:

Ta có : U2= 120 - 0.25=119.75

Áp dụng công thức : U1/I1=U2/I2 thay số ta được

120/1.5=119.75/I2

Suy ra I2= 1.5 ×119.75 / 120=1.496875
