Move the first probe to the other slot on the female end, then test both prongs, as before. Again, one test should read zero. If so, the string's wiring is intact. If you can't get a zero reading with either test, there could be a break in a wire or the fuses may have blown...
What you can do is to use aclamp meterto measure AC currents. The meter uses the electromagnetic field of AC current to measure current, and does not need to be in contact with the wire, so it is safe. The clamp needs to be placed around the wire and the reading will be displayed;...
What is the difference between PNP and NPN when describing 3 wire connection of a sensor? Most industrial proximity sensors (inductive, capacitive, ultrasonic and photo electric) are solid state. The term solid state refers to the type of components used within the sensor. Solid state electronic...
Off-grid solar is a great way to be energy efficient, but it needs proper planning. Learn how to size your solar array with our expert tips.
The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral...
I got on the road a little later than planned – this was the day after changing the clocks back to standard time and I wanted to have plenty of daylight left. At the first stop, everything went smoothly. I put up my 31ft Jackite mast with the 30.5ft random wire going to a 9:1...
The most common way to measure current is to connect theammeter(a meter to measure current) orshunt resistorin series with the circuit. An ammeter or ammeter shunt is really nothing more than a highly accurate resistor. When we place a precision resistor across a circuit, a voltage drop will...
A capacitor contains two metal plates surrounded by insulation, called dielectric. Applying voltage to the capacitor's wire terminals charges the plates. The capacitor then stores the charge until the appliance the capacitor supplies power to needs it.
When you pair your Mpow device to your phone, tablet, or laptop, the LED will become solid and stop blinking, depending on the model. Some models will also give you a verbal cue that the headphones have successfully paired. 4. Troubleshooting your Bluetooth connection ...
As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to produce acetic acid, protons and electrons. The electrons flow through a wire from the platinum electrode. The wire is connected to an electrical-current meter and to ...
