In a parallel circuit, the potential difference or voltage across each component is the same. In this case, the potential difference across each resistor is the same as across the emf source. The potential difference (V) across a resistor in a circuit can be found using Ohm's law which states V=IR, where I is the current and R is the resistance. Given that the current (I) in the 14.0 Ω resistor is 5.00 A, we can find the potential difference across the resistor, and thus across the emf source, by multiplying the resistance (R) by the current (I): V = I * R = 5.00 A * 14.0 Ω = 70.0 V So, the potential difference across the source is 70.0 Volts.
