9 Three cells of emf 5V and 10 V and 15 V have internal resistances 202 each The cells are connected in series with an external resistance R and the polarity of the 1st cell opposing those of the other two Find R if the terminal voltage across the 1st battery is 7 5 V 0 Find the equivalent resistance between A and B if each resistor has a A ww
