Question
10© UCLES 2023 0893/02/O/N/2310 Oliver connects a resistor in an electrical circuit.He measures the current as he increases the voltage across the resistor.Oliver draws a graph.001231 2 3 4voltage in Vcurrent in A5(a) Current is measured in A (amps) and voltage is measured in V (volts).Write down the unit of resistance.1 Calculate the resistance of the resistor.Include the equation used to calculate resistance in your answer
Solution
(a) The unit of resistance is Ohms (Ω).
(b) The resistance of a resistor can be calculated using Ohm's Law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I).
So, the equation is: R = V/I
However, the question does not provide specific values for voltage and current, so I can't calculate the exact resistance. If you provide these values, I can help you calculate the resistance.
