The resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms)
Explanation:
In the United States Of America the standard voltage is 120 v and their frequency is 60 Hz
Standard wall outlet voltage is 120 V
The current in the lamp is 0.5 ampere
Resistance (R) = V/ I
= 120/0.5
= 240Ω (ohms)
Thus the resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms).
Answer:
A current will not be induced.
Explanation:
The wire is not part of a closed circuit.
The electrical charges have no place to flow to.
The wall will be faster. If you charge using your computer, it is able to dedicate less power.
D.Simple Machine, is right.
Answer: 0.0054 s
Explanation:
There is an inverse relation between the frequency and the period of a wave (a sound wave in this case):
Where
Hence:
