The electric power can be determined using the relationship between the electric current and electric resistance. The formula for electric power is:

Power (P) = Current (I) x Voltage (V)

By using Ohm's law, we know that:

Voltage (V) = Current (I) x Resistance (R)

Substituting the above expression for voltage in the formula for electric power, we get:

Power (P) = Current (I) x (Current (I) x Resistance (R))

Simplifying the expression, we get:

Power (P) = I^2 x R

Therefore, the electric power can be determined using the formula P = I^2 x R, where P is the electric power in watts, I is the electric current in amperes, and R is the electric resistance in ohms.

The formula for determining electric power using resistance and electric current is defined as:

\(P\) \(=\) \(I^2\) \(\cdot\) \(R\)

\(P\): the electric power

\(R\): the resistance

\(I\): the electric current

The SI unit of electric power is: \(watt\text{ }(W)\)
