1. Write down the given information:
Voltage (V) = 6.3V
Current (I) = 1.2A
2. Use Ohm's Law formula to calculate resistance (R):
Ohm's Law: V = IR
R = V/I
3. Substitute the values into the formula:
R = 6.3V / 1.2A
R = 5.25 ohms
4. Round the answer to the nearest tenth:
The resistance of the light bulb is approximately 5.3 ohms.
step by step
A student did not know what the resistance was that a light bulb provided in her circuit. She did know that her battery had a voltage of 6.3V and the current was 1.2A. Round your answer to the nearest tenth.
