Topic : get to know voltage and how to measure
Voltmeter used measure voltage, ampere meter used measure electrical current. measure the electrical resistance use an Ohmmeter. first in the used voltmeter must be coupled in parallel with the measured potential difference or voltage. Another with ampere meter installation done by the series. Prepare in advance a series where it will do the measuring. next make sure the voltage of the electrical source types from PLN , switch in the direction of AC (alternating current ). If the source from the battery, (accumulator), or a transformer adaptor, use mode DC (direct current ). Select maximum scale third from voltmeter. In the example there are 10 V, 50 V, 250 and 1000 V for example taken 250 V. Connect the voltmeter to the tool you are going to be measured. the last in the measurements of electrical magnitudes required related with caution, especially with alternating current AC. Error procedure can cause electric sting hit.
