The red and white on the set-top box and TV on the audio / video input group docking, other groups do not pick up. Unplug the cable network from the TV to dock it with the corresponding port of the set-top box. And then the foolishness of the seal of the locust Feng Wei Wei with TV switch to AV on it.
85 can: √3 = 1732 This is the lowest mathematical knowledge, the current (I) derived: I = (Note that this is the wire diameter, not the cross-sectional area, the power line specifications are all used to represent the cross-sectional area), with the current, The Wire diameter formula: d = 08 × √I, and then use the wire diameter, the cross-sectional area of ??the wire to find out, this is the mathematical formula: radius × radius × 314; Well, this count finished, the use of power cord specifications Out Very simple, you need to remember the two formulas, one: P (electric power) = √3 × 380 (three-phase voltage) × I (current) × cosφ Another formula: foolishly dumplings dumplings sacrifice feng goose d = 08 × √I For electricians, these formulas should eat bones and melt into the blood Answer by: maxianhui120 |
