What causes an error in reading a voltmeter?
It could be when the positive wire is plugged in the negative slot and the negative wire is plugged in the positive slot. This can make the readings negative.
Why is copper used for solar energy?
electrical wire
Is length used to determine a wire's resistance?
Sort of.Resistance of a wire is usually given as "so many" oms per foot (or meter, etc).To actually determine a wire's resistance you would need a sensitive ohmmeter,OR a known voltage source and an ammeter.
How will you describe the flow of the electrons?
Current that flows in a wire is consists of electrons. The electrons bear negative charges.
How does a lemon powered clock works?
A lemon clock can work if you get two lemons stick a large nail in both of them get an eletrical clip and attach it to either the negative or positive point, you hold the copper wire in place by the eletrical clips and attasch the copper wire to the nail, on the other end the eletrical clip will be holding the copper wire attaching to the negative and positive point. If it is not working you did something wrong.
How do you charge car battery with solar charger?
Put the solar panel in the sun;Attach the red wire of the panel to the positive terminal of the battery;Attach the black wire of the panel to the negative terminal.
How do you store solar power?
You can store solar power with the help of solar panel. You can connect the solar panel with a copper and multistrand wire. It can be used for making electromagnet by connecting the wire with the metal. Written by Shubhayu Bhattacharya
How do you determine which wire on a led or capacitor is the negative end?
on an LED, the negative end is the shorter side. on a capacitor, the negative end usually has some kind of marking on it, whether its a line, or an arrow or something. with ceramic disk capacitors, there is no negative end, you just attach each side to a positive end, usually for a solar panel or something to store energy.
If you have 48 volts solar panel what kind of wire you use?
The voltage of the solar panel is less important than the total amperage. Proper wire size is determined by amperage that will be going through the wire. Wire INSULATION determines the voltage that a wire can carry.
How do you wire a fuse panel on a boat?
all the positives will go to fuse panel. The hot wire will come from battery to fuse panel. All the negatives will need to be joined together at the negative post of battery.
What materials are needed to make a solar house model?
Cardboard, red wire, black wire, some resistors and LEDs, a small motor maybe, a cellphone battery if you want to be fancy, and of course, a baby solar panel or two.
How do you construct a solar panel?
When you create a solar panel you need to have a bunch of photovoltaic cells, something to put them in, and something to protect them. Normally you can but them in a wooden casing covered with plexi glass. You then need to wire the photovoltaic cells. Then you need to find where you wish to place them and wire them to your house. For a more detailed guide check the link below.
Which wire is grounded positive or negative?
The negative wire is grounded.AnswerThe negative wire is grounded.
How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
How do you tell a positive wire from a negative wire on a car?
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
How do you tell a positive speaker wire from a negative speaker wire?
The positive speaker wire is a solid color, your negative wire should have a stripe on it.
What wire on your ignition coil on your 99 Cherokee XJ is negative?
The 1999 Jeep Cherokee ignition coil used a black wire for the negative wire. The negative wire should be on the left post.
