What is the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms?
a)1.8 A
b)45 A
c)0.022 A
d)8.8 A
To find the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms, we can use Ohm's Law, which states that I = V/R, where I is the current, V is the voltage, and R is the resistance.
In this case, the voltage is 9 volts, and the resistance is 0.2 ohms.
I = 9 V / 0.2 ohms = 45 A
Therefore, the correct answer is (b) 45 A.

Hello! How can I assist you today?
To calculate the current produced by a 9-volt battery flowing through a resistance of 0.2 ohms, you can use Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance.
In this case, the voltage is 9 volts and the resistance is 0.2 ohms.
So, the current (I) = 9 V / 0.2 Ω = 45 A.
Therefore, the correct answer is b) 45 A.
