I think you mean, 'insulation' resistance! It's the resistance of insulation, normally expressed in megohms.
B - Dynamic resistance
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
output resistance decreases and input resistance increases
A resistance that doesn't change.
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
flexibility
The isolation transformer provides a electrical mean to separate the source and load. Also, The isolation transformer will protect against surges and spikes as the primary winding due to it's magnetic property will impose more resistance (reactance) to higher frequencies such as spikes and such. where Xl is the impedance (resistance) of the primary winding. In this equation, one can see that higher frequencies increast the impedance of the coil proportionally to the rate of frequency.
1. When new species form.2. When a group is separated from the rest of its species.3. When members of the isolated group can no longer mate with the rest of species.
Three types of isolation involve mating; habitat isolation, mechanical isolation, or sexual isolation.
isolation
there are six types which are below: 1. geographical isolation 2. ecological (habitat) isolation 3. behavioral (ethological) isolation 4. temporal isolation 5. structural (mechanical) isolation 6. gamete mortality (gamete isolation)
Reproductive isolation
Geographic isolation.
Behavioral Isolation is isolation caused by differences in courtship or mating behaviors.
Prisoners used to be punished by isolation with being put in the "hole" for 30 days.Prolonged isolation affects mental and emotional well-being.Children subjected to isolation develop severe social problems.
Geographic isolation.
