A resistor has a resistance of $5,\Omega$. A current of $2,\textA$ flows through it. a) Calculate the potential difference (voltage) across the resistor. b) If the resistance is increased to $10,\Omega$ and the voltage remains the same, what happens to the current?
Circle the best answer.
A circuit has a resistor connected to a 6V battery. An ammeter shows that the current flowing through the circuit is 0.5A. Calculate the resistance of the resistor. Step-by-Step Solution: Identify the given values: State the formula: , which rearranges to Substitute the values: Calculate and state the final answer with units: Category 2: Analyzing Series and Parallel Circuits Exercise: Two identical bulbs, , are connected in series to a 12V power supply. What is the voltage across bulb If another identical bulb is added in series, what happens to the brightness of bulbs Step-by-Step Solution: f2 science electricity exercise top
