Find the number of photon emitted per second by a 25 watt source of monochromatic light of wavelength \[\text{6600 }\overset{\text{o}}{\mathop{\text{A}}}\,\text{.}\] What is the photoelectric current assuming 3% efficiency for photoelectric effect?

• A. \[\frac{25}{3}\times {{10}^{19}}J,0.4amp\]
• B. \[\frac{25}{4}\times {{10}^{19}}J,6.2amp\]
• C. \[\frac{25}{2}\times {{10}^{19}}J,6.2amp\]
• D. None of these
