What is Conductors and insulators
Conductors - one or more electrons from each atom in solid can move freely by body conducting electric charge (metals)
Insulators - electrons are strongly bound to nuclei inhibiting electric charge (plastics, rubber, and glass)
REST: A body is said to be at rest if it does not alter its position with respect to its surroundings.
Power ratings of DC Circuit: Electrical equipment can only stand a certain amount of heat production without damage and the safe power which a piece of equipment can consume wi
At 400.0 K, germanium has 1.13 x 10 15 free electrons/cm 3 . How many free electrons per Ge atom are there at this temperature? At 400.0 K, silicon has 4.54 x 10 12 free
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in the accordance with ohm’s law.
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
