#125# volts

Power is related through the equation:

#P=IV#

#I# is the current in amperes

#V# is the voltage in volts

Potential difference is basically the voltage of the circuit. So, we get:

#P=5.00*10^2 \ "W"=500 \ "W"#

Therefore,

#500 \ "W"=4 \ "A"*V#

#V=(500 \ "W")/(4 \ "A")#

#=125 \ "V"#
