3
In: Label each diagram as series or parallel:

4
Objective: To understand Ohms law and measure: Simple Series Parallel circuits Success criteria: Calculate and measure current, voltage and resistance.

5
Amount of charge passing by every second: Current I=ΔQ Δt Measured in Amperes 1 Ampere= 1 Coulomb second

6
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.

7
Energy of each charge Electric potential V measured in Volts Energy charge

8
Resistance to flow of electrons Resistance Measured in Ohms Ω

9
How do you think the current would change if you increase the resistance in a circuit?

10
How do you think the current would change in a circuit if you increase the voltage into a circuit?

11
Ohms Law Georg Simon Ohm German physicist The relationship between current and voltage 1827

12
Ohms Law V=IR

13
A lightbulb has a resistance of 240 Ω when operating at a voltage of 120 V. What is the current in the bulb?

14
A toaster has a resistance of 10 kΩ. How much current flows through it at a voltage of 120V?

15
What is the resistance of a hair dryer if it runs at 120V with a current of 1 A?

16
What is the current of a lightning bolt that has a voltage of 10 million volts through air with a resistance of 2 KΩ?

17
Lab: Using a Multimeter Purpose: to measure circuits.

18
How to measure resistance voltage and current

19
