Answer: current = 16.25A
Explanation:
Stereo = 360w, computer = 30w, laser light projector = 1200w, 3 120w- lights = 3 * 120 = 360w
Total power = 360 + 30 + 1200 + 360 = 1950W.
Voltage across the mains = 120v.
Power = current * voltage
1950 = current * 120
current = 1950/120
current = 16.25 A
The dispersive power of the material of the prism is independent of the shape, angle of prism or size of the prism. It depends only on the refractive index
of the material of the prism.
Atom absorbs energy when it goes into higher orbitals from their "Ground States"
