I have been given the formula P= VI and E= IR+ Ir now I need to make this into one formula that only contains P I R and r I don't know how to do this can someone help me please!!!!!!!
sorry I phrased the question wrong. I have two formulas p = IV and IR+ Ir= E i need to condense it into a formula in the form mx+c= y and it must only include the letters E , P, R and r
