Connecting two 12-volt batteries in series adds their individual voltages together to create a 24-volt battery pack. The series arrangement does not increase the capacity of the batteries.Know More
Connecting the positive battery post to the negative post of a second battery and then connecting the leads of the load to the remaining two battery posts results in a series connection. This is the arrangement used in most flashlights, where the batteries stack on top of one another. Connecting a series battery pack to a device designed to operate on a single battery often burns out motors and sensitive electronic parts.
Connecting batteries in parallel increases the capacity of the batteries without increasing the voltage. The parallel connection indicates the positive post and negative post of one battery connect to their corresponding post on the second one. The load then connects to the posts of one battery. A parallel battery pack allows the load to operate twice as long. Doubling both voltage and capacity of a battery pack requires connecting two two-cell series battery packs together in parallel.
Regardless of how batteries connect, it is essential to match their type and capacity. Differences in battery chemistry result in differences in battery voltage. These differences in capacity cause one battery to drain the second below the normal level. As a result, the over-drained battery is often unable to recover from the deep discharge, shortening its life.Learn more in Electrical
To wire a two-gang switch, join the live wires with a single connector, repeat the same for the black and ground wires, and attach the wires to their respective terminals in the switch. Before you begin, disconnect the power supply to the room to avoid electrocution.Full Answer >
In order to wire a two-way switch, a current tester, wire cutters, strippers, caps, a two-way switch and basic electrical knowledge are required. A two-way switch offers several benefits to the home, such as allowing one switch to control both a ceiling fan's light brightness level and blade speed.Full Answer >
A 12-gauge wire can carry between 15 and 20 amps for normal electrical wires. When wiring chassis, 12-gauge wire can carry a maximum of 41 amps along the metal conductor. The conductive part of a 12-gauge wire is 0.0808 inch in diameter. This gauge is found in extension cords.Full Answer >
The use of two-wire resistance temperature detectors with three- or four-wire instrumentation depends on the application, as this configuration adds additional uncompensated resistance to the system and seriously impairs the accuracy of the RTD. Consult the manufacturer for the proper RTD to use with its instrumentation for specific applications.Full Answer >
