Tóm tắt :
\(U=30V\)
\(U'=15V+U\)
\(I'=0,4A+I\)
\(I=?\)
GIẢI :
Hiệu điện thế U' tăng thêm 15V là :
\(U'=15V+U=15+30=45V\)
Ta có : \(\dfrac{U}{I}=\dfrac{U'}{I'}\)
\(\Leftrightarrow I'=\dfrac{U'.I}{U}\)
\(\Leftrightarrow I+0,4=\dfrac{45+I}{30}\)
\(\Leftrightarrow30\left(I+0,4\right)=45+I\)
\(\Leftrightarrow30I+12=45+I\)
\(\Leftrightarrow30I-I=45-12\)
\(\Leftrightarrow I=\dfrac{33}{29}\left(A\right)\)
Vậy cường độ dòng điện ban đầu là 33/29(A)
