Question
Identify the step which is not correct in measuring the voltage by a voltmeter.
- Plug the probes into the meter.
- Choose the electrical component along which voltage needs to be measured.
- Hold the probes by the insulated handles and touch the red probe to the positive side of the circuit and the black probe to the negative side of the circuit.
- Your voltmeter is in series to the component.
Hint:
Voltmeter has high resistance to limit its effect on the circuit.
The correct answer is: Your voltmeter is in series to the component.
- Voltmeter is the device that is used for measuring the volt in the device.
- The voltmeter is connected to the circuit in parallel series to the device.
- Because voltmeter has high resistance so it can have little affects on the circuit and only measure the voltage of the device.
