E104A - Test Quiz 1

When the switch is open, the lamp will not glow.

• True

• False

With the switch 1 closed and switch 2 open.

• no lamps on

• all lamps on

• only lamps 3 and 4 on

• only lamp 3 on

The circuit above is not correctly wired please list the problems.

• Fuse and switch are in parallel

• Fuse and switch are in series

• The volt meter is in parallel with the battery

• The volt meter is in series with the battery

The resistor is made smaller:

• current increases.

• voltage increases.

• current decreases.

• lamp will be dimmer.

The RCD:

• protects properties from circuit overload.

• uses current imbalance to shut off the power.

• remote current detection system for commercial buildings only.

• only works with dry floors.

The meter is reading:

• current.

• voltage.

• lamp brightness.

• battery capacity.

The meter is connected:

• in series with the lamp.

• as a load with the lamp.

• in parallel with the lamp.

• in parallel with the resistor.

The low meter reading is due to:

• a flat battery.

• a faulty bulb.

• a faulty meter

• a resistor.

• all of the above.

The current shown above is:

• Faraday's current.

• resistance current.

• electron current.

• conventional current.
