Calculating Resistance in a Light Bulb
Understanding Ohm's Law
Ohm's law states that V=IR, where V=voltage, I=current (amps), and R=resistance (in Ohms).
Given Data
There is a current of 0.99 A through a light bulb when its connected to a 9.7 V battery.
Calculating Resistance
Plugging the values into the Ohm's law equation V=IR:
R = V / I
R = 9.7 / 0.99 = 9.8 Ohms
Question
What is the resistance of the light bulb when a current of 0.99 A flows through it from a 9.7 V battery?
Answer
The resistance of the light bulb is 9.8 Ohms.
