An anology would be a huge water tank filled with thousands of gallons of water high on a hill. The difference between the pressure of water in the tank and the water that comes out of a pipe connected at the bottom leading to a faucet is determined by the size of the pipe and the size of the outlet of the faucet.
This difference of pressure between the two can be thought of as potential Voltage.
An analogy would be the amount of flow determined by the pressure voltage of the water thru the pipes leading to a faucet. An analogy would be the size of the water pipes and the size of the faucet. The larger the pipe and the faucet less resistancethe more water thatcomes out!
The smaller the pipe and faucet, more resistancethe less water that comes out! This can be thought of as resistance to the flow of the water current.
All three of these: Change any two of them and you effect the third. In the following equations, V is voltage measured in volts the size of the water tankI is current measured in amperes related to the pressure Voltage of water thru the pipes and faucet and R is resistance measured in ohms as related to the size of the pipes and faucet: For example, to find the Voltage in a circuit: To find the current in the same circuit above assuming we did not know it but we know the voltage and resistance: In this third example we know the current 2 amperes and the voltage 2 volts ….
Choose Type of service.Introduction For my coursework I am going to investigate “Ohms Law”. This states that the current flowing through a wire is proportional to the potential difference across it.
The resistance of a typical conducting wire is low when temperature is low and high when temperature is high.
The increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through.
