Answer: option D
Explanation: students will need to make the ammeter a component built into their circuit so that electron flow through it to measure the current, by doing so, they have to connect the ammeter in series with the resistor hence making the same value of current flow through both the ammeter and the resistor.
The value of current on the ammeter is the value of current in the resistor which is the value of current flowing in the circuit as a whole.
Answer:
1. The proton is deflected toward the east by the magnetic force, but its kinetic energy does not change
Explanation:
This is consequently because the magnetic field unlike the electric field, deflects the electron but does not change its speed or kinetic energy.
