How to estimate energy contained within a 600V 10us spike?

[tpj]

I need to estimated energy contained in a 600V 10us spike?

Can this energy be sustained by a 33.2 Kohm resistor with 0.125W power rating?

Kindly provide me the necessary calculations.

Thank you.

power = v*v/R =360000/33.2 E 3 =10.843373493975903614457831325301 W
energy = Watt *time = 10.843373493975903614457831325301 * 10E-6
=1.08433734939759036144578313253e-9

energy per second (average Power)=Energy per pulse * rep rate

the rated average Power capacity of resistor should be 2 to 5 times of this so that the temp rise is very small.

having said what you have asked for please keep in mind 1/4 w resistor (cfr or MFR) are not suitable for high voltage applications. you need resistors derigned for High Voltage.
