Worksheets3002 09 Voltage Current & Equipment Measurement
Total questions: 12
Worksheet time: 6mins
Which ammeter is mostly incorrect?
1. Closest to supply phase
2. Closest to load from phase
3. Closest to return current from load
4. Closest to return current to neutral of supply
None of them are incorrect as current is equal throughout
What current would I most likely read on meter 2 if the lamp load is 100 Ohms
230 Volts
2.3 Amps
100 Ohms
1 Amp
1 Watt
Which meter will best measure the Power
Meter 1
Meter 2
Meter 3
Meter 4
None
If I joined the red cable at A and the blue cable at B with a piece of wire (Shown with blue (white stripe) ), what would the bulb do?
It would stay on
It would switch off
The circuit breaker would trip
We create a short and the RCD would trip
The voltage would increase
If I joined the red cable at A and the blue cable at B with a piece of wire (Shown with blue (white stripe) ), what would the voltage on the bulb do?
Increase
Stay the same
Decrease

Increase
Decrease
Stay the same
Stop
What am I measuring here?
Current in AC circuit
Current in DC circuit
Nothing, doesn't work like that
What am I measuring here?
Current in AC circuit
Current in DC circuit
Nothing, it doesn't work
Would this be the correct setup configuration to measure voltage on a circuit of AC 230 V and a light bulb?
Yes
No
Depends on Light bulb size
Depends if the supply is DC or AC

Could this meter and configuration accurately measure the voltage on an AC circuit if I just flicked the switch one spot to the left? The meter is attached to measure voltage.
Yes
No, wouldn't work
It would measure, but would not be accurate
I need to move the handle setting accross to A as the meter leads are set for current
