1. Define current and state its unit of measurement.
- Current is measured in amps (A) and represents the flow of electric charge.
2. What unit is used to measure charge?
- Charge is measured in Coulombs (C), representing the amount of electric charge.
3. Describe the unit used to measure energy in electrical systems.
- Energy in electrical systems is measured in Joules (J).
4. Define resistance and state its unit.
- Resistance is measured in Ohms (Ω) and represents the opposition to the flow of electric current.
5. What unit is used to measure time in electrical calculations?
, - Time in electrical calculations is measured in seconds (s).
6. Define voltage and state its unit of measurement.
- Voltage is measured in Volts (V), representing the electric potential difference between two points.
7. Explain the concept of power and state its unit.
- Power is the rate at which energy is transferred or converted and is measured in watts (W).
8. What are the rules governing current in a series circuit?
- In a series circuit, the current is the same everywhere. Ammeter readings are consistent throughout.
9. What are the rules regarding voltage in a series circuit?
- Voltage is shared among components in a series circuit that are connected in sequence.
