Measure the voltages at given different stages given in observation table using dmm
Answers
Answer:
A digital multimeter only really "moves" to measure voltage. This fact is the basis for the operation of all other scales. The ohms scale, for instance, operates by passing a steady current across the resistance being measured. Once the voltage drop across the test resistor has been determined, the metre shows the result in ohms.
Explanation:
A digital multimeter only really "moves" to measure voltage. This fact is the basis for the operation of all other scales. The ohms scale, for instance, operates by passing a steady current across the resistance being measured. Once the voltage drop across the test resistor has been determined, the metre shows the result in ohms. Similar to the voltage scale, the current scale passes the test current via a low value shunt resistor while the metre gauges the voltage drop across it. The response is shown as current.
In reality, the fundamental circuit clocks the amount of time it takes a capacitor to charge to the input voltage. As a result, 1.500 volts is really 1.500 milliseconds that have been renamed. Because there are capacitors with a continuous current flowing, it works out quite well.
