What is the formula to calculate the potential difference (voltage) in a circuit?
$V = I \times R$, where V is the potential difference (voltage), I is the current, and R is the resistance.
What happens to the current in a series circuit when the resistance increases?
In a series circuit, if the resistance increases, the current decreases.
What is the main difference between a series circuit and a parallel circuit?
In a series circuit, components are connected in a single loop, so the current is the same throughout. In a parallel circuit, components are connected in separate branches, allowing the current to split and flow through multiple paths.
How do you calculate electrical energy used in a circuit?
Electrical energy can be calculated using the formula $E = P \times t$, where E is energy (in joules), P is power (in watts), and t is time (in seconds).
What is the purpose of a fuse in an electrical circuit?
A fuse is used to protect the circuit from excessive current by breaking the circuit if the current becomes too high.
What is the relationship between resistance and temperature for most conductors?
For most conductors, resistance increases as the temperature increases.
Explain how static electricity is produced.
Static electricity is produced when electrons are transferred from one object to another, causing an imbalance of charge. This often happens through friction, where one material gains electrons and the other loses them.
How is electricity generated in a power station?
Electricity in a power station is generated by rotating a coil of wire inside a magnetic field, which induces an electric current in the wire. This is done using turbines powered by steam, water, or wind.
What is the purpose of the earth wire in a plug?
The earth wire provides a safe route for electric current to flow to the ground if there is a fault, preventing electric shocks.
Describe the role of a circuit breaker in a household electrical system.
A circuit breaker is a safety device that automatically shuts off the electrical supply if the current flowing through the circuit exceeds a safe level, protecting the system from damage or fire.
