Question
If the circuit is constructed with a 12 V power supply and a 5.1 Ω light bulb as a resistor, how much current flows through the circuit?
Solution
To find 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).
Given: Voltage (V) = 12 V Resistance (R) = 5.1 Ω
We can substitute these values into Ohm's Law:
I = V / R I = 12 V / 5.1 Ω
So, the current (I) flowing through the circuit is approximately 2.35 Amperes.
