Why is the national grid regarded as a system
Because it is made of different parts working together to deliver electricity
Provide an explanation for the statement “Electricity that is transmitted through power lines has high voltages and low current strength”.
Electricity is transmitted at high voltages and low current to reduce energy loss during transmission. High voltage allows the electricity to travel long distances, while low current minimizes the heat generated due to resistance in the wires, thus reducing energy loss.
What is electrical power
Electrical power is the rate at which electrical energy is transferred by an electric circuit.
Hypothesis of the experiment
As the number of bulbs in parallel increases, the current strength also increases.
Heading of the graph
The relationship between the number of bulbs in parallel and the current strength
