Answer:
Explanation:
Voltage = 12 (the two batteries are in series and the voltage adds).
Resistance = 3 ohms
I = V / R
I = 12/3
I = 4 amperes.
None of the answers are the right ones. If there is a fifth one that reads 4 amperes then it is the correct answer.
Answer:
Explanation:
Given that,
Charge through a wire is
Q = 4000C
Time for charge to pass through the wire is
t = 50seconds
Then,
Current through the wire is the rate of charge passing through the wire
Q = it
Where
Q is charge.
I is current
t is time taken
Therefore,
I = Q / t
I = 4000 / 50
I = 80 Amps
The wavelength and frequency of the wave is altered, resulting in a change in the amount of energy carried.
