Question

A household circuit rated at 120 volts is protected by a fuse rated at 15 amps, what is maximum number of 100 watt ht bulbs which can be lit simultaneously parallel in this circuit without blowing the fuse? in Show calculation: L) 18 20 24 Magnets and Electromagnetism Which of these will experience a magnetic force in a magnetic field? Check all that apply a positive or negative charge at rest a moving charge moving parallel to the field a moving charge moving perpendicular to the field Which of the following cannot induce a voltage in a loop of wire? Expanding or contracting the loop in a region where there is no magnetic field. Moving the loop near a magnet. L). Moving a magnet near the loop C), Changing the current in a nearby loop. A straight wire with a length of 30 cm carries a current of TA. The wire is oriented perpendicular to a magnetic filed of 0.5 T. What is the size of the magnetic force exerted on the wire? Show calculation: A current flowing through a long straight wire causes a magnetic field that points radially outward from the wire. along the wire. along concentric circles around the wire. Calculate the magnetic flux through a square loop of12 cm x2cm oriented perpendicular Show calculation: to a magnetic filed of 0.5 A coil of wire with so turns and tional area of o.01 mi les with its plane perpendicular to a magnetic field of 1 T. The coil is rapidly removed from the field in a time of 0.2 s. What is the initial magnetic flux through the coil? What is the induced voltage in the col?

Explanation / Answer

120V*15A = 1800 W

Neglecting heat loss in the wiring, (there's always some,
but it's small), - 18 lamps.

Since you asked in 'Engineering'

The rating of that fuse is based on a set temperature, and it
will open at a larger or smaller current in a lower or higher ambient.

The rating of the 'household circuit' is based on a maximum sustained

current of 80% of the rated load.
