How much power is produced if a voltage of #2 V# is applied to a circuit with a resistance of #24 Omega#? Physics Electrical Energy and Current Electric Power 1 Answer Alan P. Feb 16, 2016 #166.bar6 " mW"# Explanation: #P=V*I# (power equals voltage time current) #I=V/R# (current equals voltage divided by resistance) #rArr P = V^2/R# In this case #color(white)("XXX")P=(2V)^2/(24 Omega)=1/6" W" = 166.bar6 mW# #color(white)("XXX")#Note on Units used: #color(white)("XXXXXX")1 " Amp" (A or "Ampere") = (1 V ("volt"))/(1 Omega ("ohm"))# #color(white)("XXXXXX")1 " Watt" (W) = 1 V ("volt") xx 1 A ("ampere")# #color(white)("XXXXXX")1000 " mW" ("milliWatts") = 1 " W" ("Watt")# Answer link Related questions What is the SI for a unit of power?
