1.
The I–V graph of an ohmic conductor is
a curve through the origin
a straight line through the origin
a straight line with a positive intercept
a horizontal line
2.
The resistance of a filament lamp increases with p.d. because
its filament gets hotter so ions vibrate more
its filament gets longer
electrons are used up
the number of electrons increases
3.
A diode in reverse bias has
very low resistance
zero resistance
the same resistance as in forward bias
very high resistance
4.
A component has coordinates (6.0 V, 0.30 A) on its I–V curve. Its resistance there is
0.050 Ω
1.8 Ω
20 Ω
180 Ω
5.
An NTC thermistor is warmed. Its resistance
rises
stays the same
becomes infinite
falls
6.
A silicon diode in series with a 100 Ω resistor and a 5.6 V supply is forward biased with 0.60 V across the diode. The current is
50 mA
