D.) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case.
Answer:
Current, I = 2.3 A
Explanation:
We have,
Voltage of the battery in a circuit is 9 volts
Resistance of the circuit is 4 ohms
It is required to find the current in a circuit. When the voltage and the resistance of the circuit is given then we can find the current in it is given by Ohm's law as :
I is electric current
or
I = 2.3 A
So, the current in the circuit is 2.3 A.
The acceleration due to gravity on Earth is 9.8 m/s per second.
