Sexual reproduction in animals is the production of a new organism from two parents by making use of their sex cells or gametes. In this process male gametes fuses with a female gamete to form a new cell called 'zygote'. This zygote then grows and develops in to a new organism in due course of time.

What happens to a circuit's resistance (R), voltage (V), and current (1) when

hammer [34]

Answer:

R increases

V is constant

I decreases

Explanation:

The resistance of a wire is given by the following formula:

$R = \frac{(Resistivity)(L)}{A}$

It is clear from this formula that resistance is directly proportional to the length of wire. So, when length of wire is increased, the resistance of circuit increases.

The voltage in the circuit will be constant as the voltage source remains same and it is not changed.

Now, we can use Ohm Law:

V = IR

at constant V:

I ∝ 1/R

it means that current is inversely proportional to resistance. Hence, the increase of resistance causes the current in circuit to decrease.

Therefore, the correct option will be:

D.

R increases

V is constant

I decreases
