a) Đây là biến thế hạ thế vì nó làm giảm hiệu điện thế

b) Có \(\dfrac{U_1}{U_2}=\dfrac{N_1}{N_2}\Leftrightarrow\dfrac{220}{6}=\dfrac{N_1}{30}\Leftrightarrow N_1=1100\)(vòng)

Bài 2:

Tóm tắt:

AB = 2cm

OA = 30cm

OF = OF' = 20cm

A'B' = ?

OA' = ?

Giải:

\(\Delta ABF\sim\Delta OIF\)

\(\Rightarrow\dfrac{AB}{OI}=\dfrac{AF}{OF}\Leftrightarrow\dfrac{AB}{A'B'}=\dfrac{OA-OF}{OF}=\dfrac{2}{A'B'}=\dfrac{30-20}{20}\)

=> A'B' = 6cm

\(\Delta OAB\sim\Delta OA'B'\)

\(\Rightarrow\dfrac{OA}{OA'}=\dfrac{AB}{A'B'}\Leftrightarrow\dfrac{30}{OA'}=\dfrac{2}{6}\Rightarrow OA'=90cm\)

\(S=2S-S\)

\(=2\left(1+\dfrac{1}{2}+...+\dfrac{1}{2^{2022}}\right)-\left(1+\dfrac{1}{2}+...+\dfrac{1}{2^{2022}}\right)\)

\(=\left(2+1+...+\dfrac{1}{2^{2021}}\right)-\left(1+\dfrac{1}{2}+...+\dfrac{1}{2^{2022}}\right)\)

\(=2-\dfrac{1}{2^{2022}}< 2\left(đpcm\right)\)
