Lesson 2
Electronics
Recap: Ohms law and resistance
SECTION 01
- There is not enough resistance in a circuit
- Current flows through components in that circuit
What happens when...
SECTION 01
Ohm's Law
SECTION 01
+ Questions
- Voltage: Volts (V)
- Current: Amps (A)
- Resistance: Ohms (Ω)
What units do we measure each of these in?
Ohm's law
SECTION 01
If you have a resistance of 3Ω, calculate the current for the voltage values below
Double the current
Double the voltage
If you have a resistance of 3Ω, calculate the current for the voltage values below
If you have a voltage of 6V, calculate the current for the resistance values below
Halve the current
Double the resistance
If you have a voltage of 6V, calculate the current for the resistance values below
Types of resistor
SECTION 02
Create a table of your answers.
- Name of resistor
- How it functions
- What is the symbol
- Common applications
Research different types of resistors. Key points to look up:

SECTION 02
What about this resistor tells us the amount of resistance it provides?
Will one type of resistor work for every circuit?
+/- 2%
x 1 Ω
Tolerance
Multiplier

"1st" column
What does each one mean?
Resistor bands
The same applies for amps: 1 kA = 1,000 A and 1 MA = 1,000,000 A
1 MΩ = 1,000,000 Ω
One megaohm is equal to 1,000,000 ohms
1 kΩ = 1,000 Ω
One kiloohm is equal to 1,000 ohms
What did you notice about the units of ohms?
See how quickly you can complete the conversion game
Match the resistors to the correct value
