Which of these could be an advantage of an analogue voltmeter
It has a battery to illuminate the scale
It is able to show variations in voltage over a short period of time
It is cheaper than a digital voltmeter
It is more robust than a digital voltmeter
Which of these is true?
Voltage is read by applying the meter in series with a component
Current is read by placing the meter in parallel with a component
Voltage and current are read by placing the meter in series with a component
Current is read by placing the meter in series with a component
In a series circuit:
the current will vary depending on the component which preceeds the meter
the current is the same in all parts of the circuit
the voltage is the same for all components in the circuit
the current is proportional to the number of components
The power used by a piece of equipment can be calculated by measuring the current and voltage. These would be measured by
placing an ammeter in series and a voltmeter in series with the equipment
placing an ammeter in series and a voltmeter in parallel with the equipment
placing an ammeter in parallel and a voltmeter in parallel with the equipment
placing an ammeter in parallel and a voltmeter in series
The Rf output power of an RF amplifier is
the same as the power used by the amplifier
more than the power used by the amplifier
less than the power used by the amplifier
the same as the heat energy generated by the amplifier
