difference across the 12.0 Ω resistor is 1.20 V, calculate the emf of the cell. 45. Req = 13.5 Ω ... (b) I = V / Reff = 1.5 / 2 = 0.75 A.
Equal parallel resistors are governed by the formula
R = r^2/(2r) = r/2
r = 2.30 * 10^-8 ohms which is very tiny.
R = 2.30 *10^-8 / 2
R = 1.15 * 10^-8 ohms. <<<< Answer
