# Electricity Formulas

Electricity is the technological impact that gives the power which makes all technological tools run like light, computers, hair dryers, cell phones, fan, etc. There are many concepts in electricity like voltage, current, resistance and many. Here are some formulas we can go through,**Power formula is given by,**

P = I$^{2}$R.

Where, I is current,R is the resistance.

**Voltage formula is given by,**

V = IR.

Where, I is the current,

R is the resistance.

R is the resistance.

**Resistance formula is given by,**

R = $\frac{E}{I}$.

Where, E is the voltage,

I is the current.

I is the current.

**Current formula is given by,**

I = $\frac{E}{R}$.

Where, E is the voltage, R is the resistance.
