|
## Voltage, current, resistance
|
|
|
|
|
|
|
|
### Voltage
|
|
|
|
$$
|
|
V = I \times R
|
|
$$
|
|
|
|
### Current
|
|
|
|
$$
|
|
I = \frac{V}{R}
|
|
$$
|
|
|
|
### Resistance
|
|
|
|
$$
|
|
R = \frac{V}{I}
|
|
$$

|
|
|
|
### Power
|
|
|
|
$$
|
|
P = V \times I
|
|
$$
|
|
|
|
### Voltage
|
|
|
|
$$
|
|
V = \frac{P}{I}
|
|
$$
|
|
|
|
### Current
|
|
