Question
The circuit in a particular toy car has a total resistance of 400 Ω and the battery is supplying 4 V. Calculate how much current, in amps (A), is flowing.
Solution
To calculate the current flowing through the circuit, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R).
In this case, the voltage (V) is 4 volts and the resistance (R) is 400 ohms.
So, the current (I) can be calculated as follows:
I = V / R I = 4 V / 400 Ω I = 0.01 A
So, the current flowing through the circuit is 0.01 amps.
