Power dissipation check
Posted: Thu Aug 09, 2012 6:57 pm
Two SMT resistors are marked as 820 and 121, and they are wired in series. An AC
voltage of 10V peak at 1kHz is applied across the pair of resistors. How much power is
dissipated in each resistor?
Am i correct in thinking the current is about 10mA, and the power dissipated is 82mW and 12.1mW for the 820ohm and 121ohm resistors, respectively?
Thanks
