PICKETTECH Workbench

A PICKETTECH new tab: quick links, eight electrical and electronics calculators, and a daily control-circuit fault puzzle.

Turn every new tab into an electrician's and electronics workbench. PICKETTECH Workbench replaces Chrome's new tab page with a clean, dark workspace built for electricians, apprentices, maintenance techs and electronics hobbyists. FAULT OF THE DAY A new control-circuit fault-finding question every day: DOL starters, forward/reverse interlocks, star-delta, overloads, contactors, timers, VFDs and earth faults. Answer it and get a short explanation of why, then keep a daily streak going. Want more? Tap "Practise another" for extra questions. 8 QUICK CALCULATORS • Ohm's law: enter any two of V, I, R or P and the rest are worked out • Resistor colour code: 4 and 5 band • Motor full-load current: three-phase estimate from kW, voltage, power factor and efficiency • Voltage drop: single and three-phase copper cable, with a % result • LED resistor: next standard E12 value, actual current and wattage rating • Voltage divider • Series and parallel resistors: type values like 10k, 4k7, 2k2 • kW to hp, both ways QUICK LINKS AND SEARCH Search the web with your own default search engine, and keep up to 12 shortcuts to the sites you use most. PRIVATE BY DESIGN No accounts, no ads, no tracking. Your links and streak are saved in your own Chrome profile only. Calculator results are estimates for learning and quick checks. Always follow the nameplate, manufacturer data and your local wiring rules.
