Question

Help! I'm not good in circuits! Can you please explain the answer to me?

Answer 1

Decreases, increases, increases.

Explanation:

To get more light, you need more electricity (current). To have more electric current, resistance LDR must decrease.

That means total resistance of the circuit decreases. If the current increases, then the current passing the fixed resistor also increases. The voltage of the fixed resistor is

V= IR

so V must increase if I increases, because R is fixed.
