Answer:
The pair of terminals to produce an output voltage of 8V are K and M.
Explanation:
A transformer is an electronic device that can be used to increase or decrease an output voltage. It consists of secondary and primary coils, and operates on the principle of induction.
=
where: is the voltage in the secondary coil, is the voltage in the primary coil, is the number of turns in the secondary coil and is the number of turns in the primary coil.
In the question, let us combine the number of turns in the secondary coil. So that,
= 15 + 5 = 20
=
=
= 8
= 8V
For the output voltage to be equal to 8V, the pair of terminals required are K and M.
Answer:
60V
Explanation: . V = IR = 1
30*2=60
kinematic equation
v=u+at
v-u=at
v-u = 1x5
the driver will have increased speed by 5 m/s. actual speeds unknown
Answer:
Lenz's law
Explanation:
The direction that an induced current flows in a circuit is given by Lenz's law. This law states that the direction of induced current is such that it will oppose the change in magnetic field that produces it. The induced emf is equal to the rate of change of magnetic flux. Induced current is given by induced emf divided by resistance.
