TRANSFORMER

Transformer adalah peranti yang digunakan untuk .......... nilai voltan.

The transformer is a device used to .......... the value of a voltage.

• memantapkan / steady

• menentang / resist

• mengubah / change

• menyelaras / anchor

Sekiranya transformer mengurangkan voltan, ia dipanggil transformer .......................

If a transformer reduces voltage, it is called a....................... transformer.

• injak kiri / step left

• injak kanan / step right

• injak naik / step up

• injak turun / step down

Sekiranya transformer meningkatkan voltan, ia dipanggil transformer .........

If a transformer increases voltage, it is called a ......... transformer.

• injak kanan / step right

• injak kiri / step left

• injak naik / step up

• injak turun / step down
