Yes, it is an electrical formula. It means electrical potential difference (volts) is equal to the product of the current (amps) and resistance (ohms).
For example, if a voltage of 100 volts is placed across a 50 ohm resistor the current through the resistor is: 100/50 or 2 amps.

Ohm's law states that E = I x R, or the voltage (E) is a product of the Current (I) and the Resistance (R). Thus if the Current increases, and the Resistance stays constant, the Voltage will increase, etc.
Can also be rewritten as: I = E/R or R = E/I.

Yes it means that the voltage across a resistor equals the resistance times the current.

The E for voltage may be a little confusing until you realize it represents ''Electrical Potential''. I have no idea where I for current comes from.

Ohm's Law
E = Voltage - measured in Volts
I = Current - measured in Amperes
R = Resistance - measured in Ohms

It's called Ohm's Law. there is no dot after the I though. It is
E=IR
E is the electromotive force or emf (measured in volts)
I is the current (measured in amperes)
R is the resistance (measured in ohms)

That is the famous Ohm's Law. It relates Voltage (E), Current (I), and Resistance (R). If you know any two of them you can calculate the third one.

It would be if E = Voltage for V = I R
