Describe briefly with used of practical knowledge the effect of the voltage stores across and current
DaniilM [7]

Answer:

Answer in explanation

Explanation:

The path of flow of circuit is called electric circuit. In an electric circuit, resistances are connected in two different ways, which are:

1- Series Combination of Resistances

2- Parallel Combination of Resistances  

<u>Series combination of resistances </u>

In series combination resistors are connected end to end, and there is only one path for the flow of current.  

Characteristics Of Series Circuit:

1. In series circuit there is only one path for the flow of current.

2. Same amount of current flows through each resistor.

I = I₁ = I₂ = I₃ = In

3. Total voltage of the battery is equal to the sum of voltages across each resistor.

V = V₁ +V₂ + V₃ + ... + Vn

4. In series combination the combined resistance of the resistors can be obtained by adding the value of each resistor.

R  =  R₁ + R₂ + R₃ + … + Rn

<u>Parallel combination of resistances </u>

Resistances are set to be connected in parallel, when each of them is connected directly from the terminals of electric source.  

Characteristics Of Series Circuit:

1.  There are more than one path for the flow of current.

2. The value of potential difference remains constant on each resistor.

V = V₁ = V₂ = V₃ = Vn

3. Total current is equal to the sum of current passing through each resistor.

I = I₁ + I₂ + I₃ +...+ In

4. Reciprocal of equivalent resistance is equal to the sum of reciprocals of resistances connected in parallel.  

1/R   =  1/R₁  + 1/R₂  + 1/R₃  + … + 1/Rn  

The circuit diagrams are in attachment.

Brainliest if right.
jeka57 [31]

Answer:

the third law (for every action there is an equal and opposite reaction).

Explanation:

The skateboarder pushes backwards on the road (that is he applies a force on the road in a direction opposite the direction of intended motion). By Newton's third law, this action of the skateboarder causes an equal reaction of the road on the skateboarder in the opposite direction. Newton's third law states that action and reaction are equal but opposite in direction. So, the road in response to this backward force pushes the skateboarder in the forward direction causing the skateboarder and the skateboard to move in the forward direction.

What are two reasons the period of Venus is shorter than the period of earth
Setler79 [48]

Answer: The planet, named after the Roman goddess of art and beauty, can actually be bright enough to cast shadows on a moonless night. It appears so close to the sun because its orbital radius is smaller than the Earth's, and because it also moves faster than Earth, its orbital period is shorter.

PLEASE HELP
Anton [14]

Explanation:

1st.

potential energy = 16 j

acceleration d t gravity = 9.8 m/s²

mass = 7 kg

we know

pe = m×g×h

16 = 7 × 9.8 × h

16 = 68.6h

16/68.6 = h

h = 2.16

2nd :

ke = 316 j

s = 10

we have

ke = 0.5×m×s²

316 = 0.5 × m × 10²

316 = 0.5 × m × 100

316 = 50m

316/50 = m

6.32 = m

m = 6.32 kg

may be check it once cuz I'm also not perfect at numericals too . I'm just 14 yo girl lol.

hope this helps :)
