F2 Science Electricity Exercise Top Jun 2026
An ammeter measures current and must be connected in series so that the total current flows directly through it. Voltmeters measure potential difference and are connected in parallel. Q2. Three resistors of
The function of a fuse in a circuit is to: A) Increase voltage B) Store charge C) Break the circuit when current is too high D) Measure power
If one appliance breaks or is switched off, the other appliances remain functional because the remaining paths stay closed. f2 science electricity exercise top
| Feature | Series Circuit | Parallel Circuit | |------------------|--------------------------------------------------|----------------------------------------------| | | One path for electrons. | Multiple paths for electrons. | | Voltage | Voltage is divided among components. | Voltage is the same across each branch. | | Current | Current is the same everywhere. | Current is divided among branches. | | Failure impact | One broken component breaks the entire circuit. | One component can fail without affecting others. | | Brightness | Bulbs are dimmer (voltage shared). | Bulbs are brighter (full voltage each). |
The fundamental rules of electricity for Form 2 include understanding that current flows from positive to negative resistance increases in series Ohm's Law ( governs the relationship between electrical properties. set of circuit diagram problems to practice identifying series and parallel connections? An ammeter measures current and must be connected

A) The rod gained protons from the cloth. B) The rod gained electrons from the cloth. C) The rod lost electrons to the cloth. D) The rod lost protons to the cloth. Three resistors of The function of a fuse
A household is billed for electricity at a rate of $0.15 per kilowatt-hour (kWh). If a 60 W light bulb is left on for 10 hours, how much does it cost to run? (Answer: Energy used = (60/1000) kW × 10 h = 0.6 kWh. Cost = 0.6 kWh × $0.15/kWh = $0.09)
A. Ampere (A) is the SI unit for electric current.
): Known as the electrical potential difference, measured in Volts ( ) using a voltmeter connected in parallel. The flow of charge, measured in Amperes ( ) using an ammeter connected in series. Resistance ( ): The opposition to current flow, measured in Ohms ( Ωcap omega Series vs. Parallel Circuits:
