Suggestions for using resistance
◆It is better to leave 1.5 times the power margin of the resistor in the circuit. For example, the voltage in the circuit is 100V, the current is 0.01A, and the calculated power is P=100*0.01=1W. At this time, if the resistor cannot be used for 1W, calculate 1*1.5=1.5 W, there is no 1.5W resistor, so 2W resistor is needed.
◆Resistance cannot exceed the maximum use voltage of the resistor during use. For example, the maximum use voltage of the resistance 1/4W 10K is V==50V, not the 250V in 4.0. Or 1/4W 1M, calculate V==500V, the highest voltage at this time is 250V in 4.0, instead of the calculated 500V, whichever is smaller.
◆Resistance is not recommended for starting resistance, metal film resistance thin film is not suitable for high voltage environment.
