Answer
The charge transferred by the spark equals to
C.
Explanation
The relationship between energy (E), the electric potential difference (V), and charge (Q) can be represented as E = QV, hence Q could be calculated as Q = E/V; 1. First, we need to ensure that the units used in the calculation are compatible. The potential difference is given in kilovolts (kV), but the energy is in joules (J). In scientific units such as the Joule, the charge is typically represented in Coulombs (C). However, kilovolts should be converted to volts (V), where 1 kV = 1000 V, thus 2.5 kV = 2500 V.2. Substituting the given values into the equation Q = E/V gives Q = 0.005 J / 2500 V. Calculate this, and you'll get Q.3. Therefore, we need CMD the above division that prompt gives Q = 0.005 / 2500 = 2e-6 C to find the charge transferred.
