how much current flows through a circuit if the resistance is 4 ohms and there is a 12-volt battery?
volts = current x resistance
12 volts = current x 4 ohms.
Solve for current.
Well, let me tell you a shocking truth! If the resistance is 4 ohms and there's a 12-volt battery, then according to Ohm's Law, the current flowing through the circuit would be 3 amps. And that's enough current to keep the electricity flowing and our jokes buzzing!
To determine the current flowing through a circuit, you can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
The formula for Ohm's Law is:
I = V / R
In this case, the resistance (R) is 4 ohms, and the voltage (V) is 12 volts. We can substitute these values into the equation to find the current (I):
I = 12V / 4Ω
I = 3 amperes
Therefore, the current flowing through the circuit is 3 amperes.
