Formula of Ohm’s Law
I = V / R
It is the measure of how much energy is used in a span of time.
Electrical Power
Rate of electrical energy trasnfer by an electronic circuit per unit of time.
Electrical Power
Named after who is the unit of Electrical power?
James Watt
Si unit of Electrical power
Watt (W) / Joule per second
Formula for Electrical Power
P = V • I
What would be the electrical power formula if the given are work (J) and time?
P = W / t
Formula of Voltage
V = W / Q
Formula of Current
I = Q / t
The heat is produced when current flows because of friction between the moving free electrons and atoms.
Power Dissipation in Resistance
At what voltage value we can die?
42 V
The quantity that can cause us death.
Current
Why wires and electrical components are permanently placed at the circuit board?
So it won’t be easily moved and disconnected.
Early version of a circuit.
Prototype
It is the process of conmecting the circuit permanently on a circuit board.
Soldering
What can we use to check if the connection in circuit is working?
- Simulation apps
- Breadboard
It tests, runs, and checks if your circuit is working. Sometimes in a schematic diagram.
Simulation apps
Rectangular plastic board with a bunch of tiny holes where we can insert electrical components.
Breadboard
This is the msterial that is inside the breadboard. It is connected by rows and columns to secure particular connection.
Metal clips
Charges in the terminal of breadboard.
Positive and Negative
LED means
Light emitting diode
Polarities of a LED
Cathode (-)
Anode (+)
Mnemonics for Conversion Unit

Full Formula of Power Dissipation in Resistance
P = V * R = I² * R = V² / R
