Voltage across a conductor is directly proportional to the current flowing through it, provided temperature remains constant. Formula:

If the current passing through Bulb X is 0.5 A, what is the current passing through Bulb Y? Calculate the voltage drop across Bulb X. f2 science electricity exercise top

Think of electricity like water flowing through pipes; resistors are tight spaces, and voltage is the pressure. Voltage across a conductor is directly proportional to

In a series circuit, resistors (bulbs) are added end-to-end, which increases the total resistance and decreases the overall current. Correct Answer: D Plastic has very few free electrons, making it a good . Copper, silver, and graphite are conductors. Part B & C Step-by-Step 1. Using Ohm's Law is Voltage, is Current, and is Resistance). Calculation : The current is 2. Circuit Differences : There is only Think of electricity like water flowing through pipes;

): The rate of flow of electric charge. It is measured in Amperes (A) using an ammeter connected in . Voltage / Potential Difference (
