Materials (mostly metals) that allow electricity to flow easily because they contain free electrons .
One of the "top" exercise topics in F2 Science is distinguishing between series and parallel circuit behaviors. Series Circuit Parallel Circuit Single path for current Multiple branches/paths Current ( ) Same at all points Sum of currents in branches equals total current Voltage ( ) Shared across components Same across each parallel branch Failure One break stops the whole circuit One branch can break while others stay on Usage Decorative lights (old) Household wiring 3. Calculation Practice: Ohm’s Law Most "top" exercises will require you to apply Ohm's Law : V=I×Rcap V equals cap I cross cap R Example Problem Question: If a circuit has a battery and a resistor of , what is the current flowing through it? Step 1: Identify given values Step 2: Rearrange the formula for f2 science electricity exercise top
