Attatched question

A 12-V DC automobile head lamp is to be used on a fishing boa
system. The head lamp is rated at 50 W. A resistor is to be connected in
lamp to permit it to operate on 24 V. What should be the resistance and power rati g
the resistor?
PRACTICAL APPLICATION
Three wire-wound resistors have the following values: 30 2, 80 2, and 100 2. Each resis
has a voltage rating of 100 V. If these three resistors are connected in series, can the be
connected to a 240-V circuit without damage to the resistors? Explain your answer.
PRACTICAL APPLICATIONS
You are an electrician working in an industrial plant. A circuit contains eight
incandescent lamps connected in series across 480 volts. One lamp has burned
out, and you must determine which
