1.
Resistors of 10 Ω and 30 Ω are in series. The ratio (p.d. across 30 Ω) : (p.d. across 10 Ω) is
1 : 1
3 : 1
1 : 3
1 : 30
2.
A 12 V supply is across 100 Ω and 300 Ω in series. The p.d. across 300 Ω is
9.0 V
3.0 V
4.0 V
12 V
3.
With an LDR in a divider, the output p.d. across the fixed resistor increases in bright light because
the LDR resistance rises
the cell is stronger
the current stops
the LDR resistance falls
4.
Two equal resistors form a divider across 8.0 V. The output across one of them is
8.0 V
2.0 V
4.0 V
0 V
5.
Connecting a low-resistance load across the output of a potential divider
raises the output p.d.
lowers the output p.d.
makes no difference
doubles the supply
6.
The output of a potential divider always lies
between 0 V and the supply p.d.
above the supply p.d.
below 0 V
at exactly half
