Show Easy to Recharge From Direct Current Mains There are battery chargers for changing chang-ing alternating current to direct current cur-rent and others for changing the direct current at high voltage to direct current cur-rent at low voltage (6 volts). If the home Is fed from an alternating current system the first of these chargers charg-ers Is essential. They operate from any standard socket and most of them are quite noiseless In operation. But if the home Is lighted from direct di-rect current mains and many houses in the larger cities fall within the districts dis-tricts covered by direct current the radio battery may be recharged without with-out the purchase of the costly chargers. Five 100-watt lamps, five receptacles recep-tacles and a four-inch board on which to mount the lamps, complete the equipment. The lamps are connected In parallel, that Is, all the terminals on one side of the socket are connected together and all the other terminals connected together. Then a tap Is taken from each of these bus bars and connected to the lighting circuit. A battery charger of this type will charge a battery at the rate of foul to five amperes. |
