Ohm's law

R = \frac{​ U ​ ​}{​ I ​}

Slide 5 - Slide

Ohm's law

R: resistance(Ohm, Ω)
U: potential difference (volts, V)
I: current (ampere, A)

R = \frac{​ U ​ ​}{​ I ​}

Slide 6 - Slide

Ohm's law

R = \frac{​ U ​ ​}{​ I ​}

Slide 7 - Slide

Power

Slide 8 - Slide

Power

Slide 9 - Slide

Power

Slide 10 - Slide

Power

the amount of energy transferd per second.
Joule per second.
Unit: Watt

Slide 11 - Slide

Power

P = I \cdot U

Slide 12 - Slide

Power

P: Power (Watt, W — J/s)
I: Current (Ampere, A)
U: Potential difference (Volt, V)

P = I \cdot U

Slide 13 - Slide

Power

P = I \cdot U

\frac{​ C ​ ​}{​ S ​}

\frac{​ J ​ ​}{​ C ​}

Slide 14 - Slide

Power

P = I \cdot U

\frac{​ C ​ ​}{​ S ​}

\frac{​ J ​ ​}{​ C ​}

\frac{​ J ​ ​}{​ S ​}

Slide 15 - Slide

The formula's we covered.

Ohm's law:

Power:

P = I \cdot U

R = \frac{​ U ​ ​}{​ I ​}

Slide 16 - Slide
