i) Resistance and current are inversely proportional //The higher the resistance, the

lower the current// the ammeter reading decreases when the resistance increases

Rintangan dan arus berkadaran songsang// Semakin tinggi rintangan semakin

rendah arus// Bacaan ammeter menurun apabila rintangan bertambah.

ii) 0.37 0.01 A
