Question 4c
The student obtains this graph for a filament lamp.
Calculate the resistance of the lamp when the voltage is 6.0 V.
Give the unit.
Solution
To calculate the resistance of the lamp when the voltage is 6.0 V, we need to use Ohm's Law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I).
However, the information provided does not include the current at 6.0 V. If you have a graph, you should be able to find the current at 6.0 V by looking at the y-axis value that corresponds to 6.0 V on the x-axis.
Once you have the current, you can calculate the resistance using the formula:
R = V / I
Substitute the given voltage and the current you found into the formula to find the resistance. The unit for resistance is Ohms (Ω).
