What equation describes conservation of charge?
Phantasy [73]

Answer:

The equation which describes conservation of charge is Q_{initial} - Q_{final } = 0

Explanation:

The law of conservation charge states that for an isolated system that sum of initial charges is equal to sum of final charges, that is the total charge is conserved.

let the sum of initial charges = Q_{initial}

let the sum of the final charges = Q_{final}

Q_{initial } = Q_{final}\\\\Q_{initial } - Q_{final} = 0

Therefore, the equation which describes conservation of charge is Q_{initial} - Q_{final } = 0
