Answer:
To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.
Answer:
Explanation:
Voltage and current in resistors
A graph of current against potential difference shows you how the current flowing through a component varies with the potential difference across it. The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it.
