you take the peak voltage and divide it by the square root of 2
100/1.414= 70.7 volts rms
This is true only for sine wave. For other waveforms like a triangle signal it is different.
•Measures each point in a single cycle of a signal relative to its point of originPhase tells you the delay in a signal
There is no equation for Ohm's Law. Ohm's Law simply tells us that, for ohmic or linear materials, the ratio of voltage to current is a constant.The equation you are, presumably, looking for is derived from the definition of the ohm, not from Ohm's Law, and that is resistance is voltage divided by current.
Electric current can flow in one of two directions in a wire; with alternating current, the direction changes continually, back and forth. The use of positive and negative values for voltage gives you a direction for the voltage. If current flowing to the right is positive, then current flowing to the left is negative.============================Answer #2:A negative reading indicates that the point to which the positive probe ofthe voltmeter is connected is at a lower potential than the point to whichthe negative meter probe is connected. It tells nothing about the circuitconditions except in combination with the knowledge of how the meteris connected.
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
A capacitor meter measures the value of a capacitor in pf (picofarads), nf (nanofarads), uf (microfarads) or even farads. There are a million uf in a farad, 1000 nf in a uf, and 1000 pf in a nf. A farad is a very large amount of capacity. The capacity tells you how much energy the capacitor can store from a voltage source.
100v divided by 1.41
Voltage is a measure of electrical potential. I understood voltage best when my first semester Electronics professor told the class that voltage is to an electrical circuit as water pressure is to a plumbing "circuit".
it tells you how many beats are in the measure
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
it tells you how and they measure it
They're not! The relationship you describe is derived from the definition of the ohm, not from Ohm's Law. This tells us that resistance is equal to the voltage divided by the current. Ohm's Law merely tells us that the ratio of voltage to current is constant for variations in voltage -which, unfortunately, is not actually true. In other words, Ohm's Law is not true!
range
its a unit
A printer usually has an error button that lights up or a message that gives a technician an idea of the problem. They are then able to work on the printer to restore it to working.
A time signature tells you how many beats are in a measure, the top number tells you how many beats are in a measure, and the bottom number tells you what type of note gets 1 beat. For example: 3/4, 3 beats in a measure and a quarter note gets one beat.
It tells us how to measure the length of the vectors.
Temperature is the quantity that tells how hot something is. It is a measure of the average kinetic energy of particles in a substance.
