The electric power developed by the lamp will be 5 watts. Electric power is found by the multiplication of voltage and electric current.
Electric power is the product of the voltage and current. Its unit is the watt.
The given data in the problem is;
The voltage is,V = 10 volt (V)
The electric current is,I = 0.5 ampere (A)
The formula for the power is given as;
[tex]\rm P= V I \\\\\ P= 10 \times 0.5 \\\\ P= 5 \ watt[/tex]
Hence electric power developed by the lamp will be 5 watts.
