Objective: To understand Ohms law and measure: Simple Series Parallel circuits Success criteria: Calculate and measure current, voltage and resistance.
Amount of charge passing by every second: Current I=ΔQ Δt Measured in Amperes 1 Ampere= 1 Coulomb second
If a current of 80.0 mA exists in a metal wire, how much charge goes through in 10 minutes? How many electrons flow past a given cross section of the wire in 10.0 min? Sketch the direction of the current and the direction of the electrons motion.
Energy of each charge Electric potential V measured in Volts Energy charge
Resistance to flow of electrons Resistance Measured in Ohms Ω
How do you think the current would change if you increase the resistance in a circuit?
How do you think the current would change in a circuit if you increase the voltage into a circuit?
