The TV, the power consumption of which is 150 W, operates on a 220 V network. What fuse should be installed in the TV, if a 0.5A, 1A, 2A fuse is available
To determine the fuse for installation in the TV used, we apply the formula: Ipot = Pmax / U, where Ipot is the rated operating current of the installed fuse (must be selected from the standard range, its value must be higher than the calculated one); Рmax – maximum power (taken with a margin of 20% of the power consumption (Р = 150 W)); U – mains voltage (U = 220 V).
Calculation: Ipot = Pmax / U = 1.2P / U = 1.2 * 150/220 = 0.818 A (the nearest higher value is I = 1 A).
Answer: A 1 A fuse must be installed in the TV used.
