When an electrical charge flows through a(n) ________, it transfers some energy to the thermal energy store of the filament which is designed to heat up.
New cards
2
Ohmic conductors
________ have a constant resistance.
New cards
3
V Characteristics
The term I- ________ refers to a graph which shows how the current flowing through a component changes as the potential difference across it is increased.
New cards
4
Non linear components
________ have a curved I- V characteristic.
New cards
5
The calculate the resistance you can do
R=V/I
New cards
6
constant resistance
Ohmic conductors have a________
New cards
7
ohmic conductors
The resistance of________doesn't change depending on current
New cards
8
a graph which shows how currents changes as potential difference increases
The term I-V characteristics refers to_____________
New cards
9
directly proportional to potential difference
Current in ohmic conductors are______
New cards
10
temperature increases, so the resistance increases, which means less current flows per unit pd,
As the current in a filament lamp increases__________so graph gets shallower
New cards
11
will only flow in one direction, diode has a high resistance in reverse direction
In diode the current___________
New cards
12
Linear components
__________have an I-V characteristic thats a straight line
New cards
13
Non-linear components
____________have a curved I-V characteristic
New cards
14
alters the current flowing and potential difference
A variable resistor____________
New cards
15
diode
For_____, resistance depends on direction of the current, way is fine but they have a high resistance if reversed
