Ohm’s Law & Power Formulas
Ohm’s Law: Ohm’s Law states that Electromotive Force (Voltage) is equal to Current multiplied by Resistance. $$E_{volts(V)}=I_{amps(A)}times R_{ohms(Omega)}$$ Simplified: $$E=Itimes R$$ We can now manipulate the above equation to solve for Current. $$I_{amps(A)}=frac{E_{volts(V)}}{R_{ohms(Omega)}}$$ Simplified: $$I=frac{E}{R}$$ And also Resistance. $$R_{ohms(Omega)}=frac{E_{volts(V)}}{I_{amps(A)}}$$ Simplified: $$R=frac{E}{I}$$ Power Formulas: The power formula states that Power is equal to Electromotive Force multiplied …
