Practical Construction and Testing module quiz: breadboard and stripboard, the multimeter and fault-finding (O-Level Electronics) quiz

It is permanent and cannot be changed

It needs no power supply

It conducts better than any other board

Components can be inserted and rewired quickly with no soldering, ideal for testing

By soldering them to parallel copper strips on the back

By pushing them into spring clips

With no electrical connection at all

Only with screw terminals

To make the board longer

To break the connection where two parts of the circuit must be separated

To add resistance

To store charge

In series with the component

With the power switched off

In parallel across the component

Across the supply on the current range

In parallel across the component

Without making any connection

Across the supply terminals

In series, by breaking the circuit to insert the meter

Isolate the component or switch the power off

Increase the supply voltage

Connect the meter in series with the live circuit

Short the component out

The output transducer

The power supply and its connections

The colour codes of every resistor

The room temperature

A correctly oriented diode

A dry or bridged solder joint

A neatly cut wire

A resistor of the correct value

To make the circuit run faster

To increase the supply voltage

Because a measurement that disagrees with the calculation points to the fault nearby

Because measurements are always wrong

The resistor is too small

There is a short across the resistor

The supply is too high

The LED is open circuit or fitted the wrong way round

Whether there is an unbroken conducting path, often with a beep

The exact resistance value of a resistor

The supply voltage

The current through a load

To make it look neater

To confirm it behaves as the design intended under the stated conditions

To use up the battery

Because the specification is irrelevant once built
