Sam, an electrician, wraps a copper wire with a thick plastic coating. What is he most likely trying to do?
a
keep a current from passing out of the wire
b
keep the electric potential of the wire balanced
c
decrease the wire’s resistance
d
increase the voltage produced by the wire
a. keep a current from passing out of the wire
a) keep a current from passing out of the wire
Sam, the electrician, is most likely trying to option a: keep a current from passing out of the wire.
The thick plastic coating wrapped around the copper wire acts as an insulator, preventing the current from escaping or leaking out of the wire. This is useful in electrical systems where the wire needs to transmit electricity without any loss or leakage. The plastic coating effectively isolates the copper wire, ensuring that the current flows only along the intended path and minimizes any potential loss or short-circuiting.
