Physics is for hot girls ྀིྀིྀིྀིྀིྀིྀིྀི And I love physics
1
Q
What is Ohm’s law?
A
Is the relation between the three basics magnitudes in all electric circuits.
2
Q
Explain how is current directly or inversely propotional
A
- Current is directly proportional to voltage
- Current is inversely propotinal to resistance
3
Q
Calculate current
- If 45V and 90Ω
A
45V/90Ω= 0.5 A
4
Q
Calculate Resistance:
- If 230 V and 0.20 A
A
230V/0.20A= 1.150 Ω
5
Q
Calculate Voltage
- 45Ω and 0.1 A
A
45Ω/0.1A= 4.5 V
