_ 1) The majority of the radiation emitted to the general public during the normal operation of
a nuclear power plant comes from:
A. cooling water discharged to a lake or a river.
B. fission-fragment gases that e

Name _
_ 1) About how much current is drawn by a 1500 W appliance operating at 125 V?
A. 2 amps
B. 8 amps
C. 12 amps D. 15 amps E. 24 amps F. 30 amps
Since P = IV, the current will be I = P/V = 1500 W / 125 V = 12 amps.
