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.
