Apply: The light bulb is also a resistor. Place the light bulb in the circuit, then use Ohm’s law to find the resistance of the light bulb. What is it?
V = 30, l = 2
First, let's clarify the given values:
V = 30 (this represents the voltage across the light bulb in the circuit)
I = 2 (this represents the current flowing through the light bulb in the circuit)
Now, we can apply Ohm's law to find the resistance of the light bulb:
Ohm's Law: V = I * R
Substitute the given values:
30 = 2 * R
Divide both sides by 2 to solve for R:
R = 30 / 2
R = 15
Therefore, the resistance of the light bulb is 15 ohms.
