Why would receptacles have low voltage and the light switches no voltage on the same circuit?

lighting is usually on 15A breakers receptacles on 20A the probability is high that they are not on the same circuit. if they are the same circuit the probability is high that there hasn't been an electrical inspection


What benefit is there for getting higher open circuit voltage?

There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.


What is open circuit voltage when load is connected?

As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.


What is voltage also known as?

The term, 'voltage', is synonymous with 'potential difference'.Originally, the term 'voltage' was used to describe potential difference when specifcally expressed in volts. These days, however, we use the term whatever multiples or submultiples of volts are used -so it applies to potential difference whether expressed in microvolts, millivolts, volts, kilovolts, megavolts, etc.It's very important to understand that voltage is synonymous with 'potential difference', and not'potential'. So it would be quite incorrect to describe, say, the 'voltage at a point' in a circuit (e.g. "...the voltage at point A in a circuit is +12 V").


What does resistance in an electrical circuit mean?

i dont know really, thats why im asking right

Why would the volts increase from the main panel to the sub panel?

Check the battery voltage on your tester. The voltage on the panel is the same throughout the whole electrical system.


Why would one electrical outlet be lower voltage than all the others?

because the circuit has to many outlets on it


What does it mean when the circuit tester light does not come on when touching the black and white wires?

It could mean two things. The first thing would be that the tester is not working. Test on a circuit that you know to be energized. The second thing causing a tester not to light is that the circuit under test is de energized. When using these types of testers always test the black to white wire and then black to ground wire. If the tester indicates there is a voltage to ground and not the white then the neutral white wire is open somewhere in the circuit.

What part of circuit is not necessary for the circuit to be complete?

By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.

Describe the relationship of the parts of an electrical current?

I assume you mean Voltage, Current and Resistance. Voltage (E)or electromagnetic force is the electrical pressure or force that forces the electrons through any given circuit Current (I)is the flow of those electrons through any given circuit Resistance (R) is anything within the circuit that would restrict the flow of electrons


What instrument would you use to test for an open circuit?

The general answer is that a continuity tester is used to check for an open circuit.


What is a sentence for voltmeter?

A voltmeter is a device used to measure the voltage in an electrical circuit. An example sentence would be: She went to the hardware store to purchase a voltmeter.


What do you nned to make an electric current?

An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.


Does height cause current in an electrical circuit?

There has been some evidence that there is an increasing voltage relative to ground with increasing altitude. Creating any electrical power would be a matter of design engineering.
