[1] A device in a 120 V circuit has a current rating of 20 Amp. Determine the resistance of this device.

[2] Determine the current that flows in a 300 watt lightbulb when connected to 120 V circuit.

[3] Determine the resistance of the 300 watt lightbulb in the previous problem.

[4] A video game console requires 6.00 V to operate correctly. A transformer allows the device to be powered from 120 V outlet. If the primary has 500 turns, determine how many turns should be in the secondary.

[5] For the video game problem presented before, determine the output current if the input current is 0.1 A. Determine the resistance of this device.

[6] For a particular patient, a nurse counts 72 heartbeats in one minute. Determine the frequency and period of heartbeats for this patient.

[7] Microwave ovens typically cook food using microwaves with the frequency of about 3.00 GHz (1 GHz = 10^9 Hz). Determine the wavelength of these microwaves.

[8] Electrons on a radio broadcasting tower were forced to oscillate up and down an antenna 535,000 times each second. Determine the wavelength of the radio waves that are produced.

[9] Blue-green light has a frequency of about 6.00 x 10^14 Hz. Determine its wavelength. Compare this wavelength to the size of an atom (about 10^-10 m) by calculating the ratio: wavelength/(atom size).
