Answer:
Current is half
Voltage is half
Explanation:
according to Ohms law V = IR
Case 1
I₁ = V / R
I₂ = V / (R+R) = V / 2R
∴ I₁ / I₂ = (V/R) / (V/2R)
=> I₁ / I₂ = (V/R) * (2R/V)
=> I₁ / I₂ = (2VR / RV)
I₁ / I₂ = 2
I₂ = I₁ / 2
The current through each resistor in the two-resistor circuit is half the current through the resistor in the one-resistor circuit (the circuit in Part A).
The voltage across each resistor in the two-resistor circuit is half the voltage across the resistor in the one-resistor circuit.
Answer:
See description
Explanation:
Frist we need to know the longitude of tape which is unwinding. Such relationship can be obtained with arc length. An arc length is the distance bewteen two points in a curve.
The relationship is:
Where is the arc length or distance, theta is the angle that results from the initial point of the measure to the final point, and r is the radius of a circumference.
Now let be length the unwinded tape. Change by and you ge the relationship:
if you unwind the tape by one revolution () you get the perimeter of a cricle , if you unwind it two times then and so on.
Then we have that the derivative of is
so we replace:
the derivative of theta with respect to t is ω(t) by definition:
The result is the relationship between angular velocity and the velocity and tangential velocity at the point r
Answer:
we will have induced magnetic field towards us
now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.
Explanation:
As per lenz law we know that the rate of change in magnetic flux linked with the closed loop will induced EMF in the loop and the direction of this induced current in the loop will always oppose the causes due to which it is induced
Here we know that magnetic field is straight towards us and it start decreasing with time
So we can say that flux linked with the coil will also decrease with time
Now as per lenz law the induced magnetic field of the loop is in such a direction that it will increase the magnetic flux in the coil.
So we will have induced magnetic field towards us
now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.
