Let's call R the value of the resistance of the two resistors. In the first situation, the resistors are connected in parallel, so their equivalent resistance is given by:

which means:

And calling I the current in the circuit, the voltage is given by Ohm's law:

In the second situation, the resistance of each resistor is doubled: R'=2R. So, the equivalent resistance in this case is given by

which means

And the new voltage is given by:

<span>which is twice the original voltage, so the voltage has doubled.

Ans: Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object. The classic example of potential energy is to pick up a brick.
Answer:
b) field is zero, c) the magnetic field does not change in intensity or direction
e) M = -H = Bo /μ₀
, g) M = 0
Explanation:
Part b
superconductors are formed by so-called Coper pairs that are electrons linked through a distortion in the network, this creates that they must be treated as an entity so we have an even number of charge carriers and the material must behave with diamagnetic , Meissner effect, consequently the magnetic field inside its superconductor is zero
the correct answer is Zero
Part c
outside the superconducting cylinder the magnetic field does not change in intensity or direction
Part E
Magnetization is defined by the equation
B = μ₀ (H + M)
with field B it is zero inside the superconductors
M = -H = Bo /μ₀
where Bo is the magnetic induction in the normal state
Part g
As outside the cylinder there is no material zero magnetization
M = 0
