Classification according to the way materials react to the current when a voltage is applied across them
Insulators
1. Materials with very high resistance
2. Oppose the flow of current (mica , rubber)
Conductors
1. Materials with very low resistance
2. Allow the current ti flow easily (copper, aluminium)
Semiconductors
1. Neither good conductors nor insulators (silicon, germanium)
2. Can be controlled to either insulators by increasing their resistance or conductors by decreasing their resistance
Supplication when leaving the home

| In the name of Allah, I place my trust and reliance to Allah and there is no might no power except with Allah. O Allah, I take refuge with You lest I should stray or be led astray, or slip or be tripped or oppress or being oppressed or behave foolish by or be treated foolishly.  |
