What Is Voltage Measured With
Voltage is one of the fundamental parameters associated with any electrical or electronic circuit.
What is voltage measured with. Voltage is seen widely in specifications of a host of electrical items from batteries to radios and light bulbs to shavers and on top of this it is a key parameter that is measured within circuits as well. A neat analogy to help understand these terms is a system of plumbing pipes. Voltage is measured in volts current is measured in amps and resistance is measured in ohms. The voltage is equivalent to the water pressure the current is equivalent to the flow rate.
9 v batteries rarely provide a full 9 v to measure voltages in the led circuit spin the multimeter dial to a range whose maximum is at least 10 v. In this case the voltage is measured across the battery. For example you can insert a voltmeter into the led circuit so that you can measure voltage. The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery.
In brief voltage pressure and it is measured in volts v. Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light. The voltmeter can measure the dc voltage of a battery for example typically 1 5v or 9v or the ac voltage from the power socket on the wall typically 120v. For more complex signals an oscilloscope can be used the measured the dc and or ac voltage for example to measure the voltage across a speaker.
It should read in the vicinity of 8 3 v. Voltage measures the relative amount of energy that will be carried by the electrical charge in a circuit it is expressed by the equation v w q where w is the energy in joules and q is the.
