hello all, how to determine wattage for the resistor for the following input condition.
the total time of signal length is 1.5second. the signal starts with a peak current of 70 amps for a period of 1ms and falls to 4 amps. after 1 second the current rise to 40 amps for period of 0.1s and falls to zero. the voltage of the input is 12v.
for the above condition how to calculate power consumption and select suitable wattage.
thanks in advance.
