Mwa njira, mphamvu ya TV ikuwerengedwa mu watts, kapena W, mwachidule nthawi yowonjezera - W / h.
Kuwonjezera apo, kugwiritsa ntchito mphamvu kumatsimikiziridwa ndi mtundu wa "chipangizo cha buluu". CRT yamakono yomwe imakhala ndi tube ya cathode ray imagwiritsa ntchito makina 60 mpaka 100 pa ora (malingana ndi kinescope m'mimba mwake). Mwachitsanzo, ngati mumayang'ana TV tsiku lililonse kwa maola asanu patsiku, ndiye kuti tsiku lililonse lopangidwa ndi chipangizochi lidzakhala la 0,5 kW / h, ndipo mwezi - 15 kW / h.
