Jawaban:
[tex]\eta = 16,36 ^o/_o\\[/tex]
Penjelasan:
Efisiensi Charger
[tex]\eta = ( \frac{P_{out} }{P_{in}} ) \times 100 ^o/_o\\\eta = ( \frac{V_{out} \cdot I_{out} }{V_{in} \cdot I_{in}} ) \times 100 ^o/_o\\[/tex]
diketahui
[tex]V_{in} = 220 \: volt\\I_{in} = 0,5 \: A\\V_{out} = 9 \: volt\\I_{out} = 2 \: A[/tex]
ditanya
efisiensi, [tex]\eta[/tex] = ?
