What is voltage, and what is its relationship to amperage and power?
1 answer:
Explanation:
Amperage is the unit of electric current. It describes the strength of the electric current in a circuit.
The voltage is the driving force of the current in a circuit
Power is a function of voltage and current in the circuit.
Current is designate as I
Voltage as V
Power as P
I =
Where R is the resistance to flow of electricity
P = I x V =
The unit of power is watts and voltage is volts

Answer:
Explanation:
It is given that, a proton moves at constant velocity, through a region in which there is an electric field and a magnetic field such that,
The electric field is, E = 800 V/m
Magnetic field, B = 0.25 T
We know that the net force in the region of magnetic and electric field is given by Lorentz forces. But here, the proton moves with constant velocity. So, the net force acting on it is 0.
i.e.
Hence, this is the required solution.
Answer:
The answer is: 212.3112
Explanation:
-First we need to know that if we want to push in order for the sled to move with constant velocity so there is no acceleration and hence the sum of forces is equal to 0.
-Second we need to know:
Friction force = Normal Force x kinetic friction
Normal force = Weight x cos(21°)
-Third:
Finally:
