crease the charge time of the circuit, for this reason, we will increase the resistance and increase the capacitance of the capacitor.

Explanation:

This system is an RC circuit, in these circuits when solving the equation, for this demoninator called charging time

τ = RC

the counter revolutionary the charge is

I = I₀ (1 - e (-t / RC))

When the light is on very fast we can increase the denominator, that is to say, increase the charge time of the circuit, for this reason, we will increase the resistance and increase the capacitance of the capacitor.
