Answer:
The splitting up of light into its constituent colours while passing from one medium to the other is called dispersion.
Answer: Voltage, V=120V; Power,P=10kW or 10,000W
P = V*I (where I is current)
∴ I = P/V =10000/120 = 83.3A
Resistance, R = V/I = 1.44 ohms
Power Factor(cosФ)= 0.9 = Resistance, R/Impedance, Z
∴ Z = 1.44/0.9 = 1.6 ohms
Explanation: The three-phase inductive load supply carries alternating current of the same frequency and voltage amplitude relative to a common reference but phase difference of one third of a cycle between each of three voltages and currents.
