Electricity and Circuits quiz for Singapore N(A)-Level Science (Physics) (SEAB 5105/5106) quiz

The energy given to each charge

The total charge stored

The opposition to charge flow

The rate of flow of electric charge

Gains electrons

Gains protons

Loses electrons

Loses neutrons

$0.4\ \text{C}$

$40\ \text{C}$

$2.5\ \text{C}$

$14\ \text{C}$

$V = I/R$

$V = R/I$

$V = IR$

$V = I + R$

$27\ \Omega$

$12\ \Omega$

$0.33\ \Omega$

$3.0\ \Omega$

The ohm

The ampere

The volt

The watt

$P = V/I$

$P = VI$

$P = I/V$

$P = V + I$

Largest near the battery

Zero in the middle

The same at every point

Different in each component

$2.0\ \Omega$

$2.9\ \Omega$

$35\ \Omega$

$12\ \Omega$

They add up to the supply voltage

Each equals the supply voltage

They are all zero

They are larger than the supply voltage

$3.0\ \text{V}$

$6.0\ \text{V}$

$12\ \text{V}$

$0\ \text{V}$

To save on wire

To make the current the same in every appliance

So each appliance gets full voltage and works independently

So that one failure switches everything off

$57.5\ \text{W}$

$226\ \text{W}$

$234\ \text{W}$

$920\ \text{W}$
