The correct answer is 110 W.

• The Power of the bulb is 110 W.
• Here the potential of the generator = 220 V
• Current flowing across the electric bulb I = 0.50 A
• Therefore Power of the bulb \(P = V * I\)
• \(P = 220 * 0.50 = 110 W\)

• Ohm's law equation (formula): V = I × R and the power-law equation (formula):
• I or J = international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

Here,   Ptential of the generator, V = 220 VCurrent flowing across the electric bulb, I = 0.50 ATherefore, Power of bulb, P = VI                          =  220 V x 0.50 A

                         = 110 W.
