ASU PHY 101 FINAL EXAM QUESTIONS AND VERIFIED
ANSWERS
Watts = - CORRECT ANSWER✅✅✅amperes x volts
Power = - CORRECT ANSWER✅✅✅current x voltage
Gravitational Field - CORRECT ANSWER✅✅✅alteration in space surrounding masses
Electric Field - CORRECT ANSWER✅✅✅the space around every electric charge, an energetic aura
that extends through space (with both magnitude and direction)
electric potential - CORRECT ANSWER✅✅✅also potential,
electric potential energy/amount of charge
Voltage - CORRECT ANSWER✅✅✅unit of measurement for electric potential
1 volt = - CORRECT ANSWER✅✅✅1 Joule/1 Coulomb
Conductor - CORRECT ANSWER✅✅✅any material with free charged particles that easily flow
through it when an electric force acts on them
Potential difference - CORRECT ANSWER✅✅✅when the ends of an electrical conductor are at
different electric potentials
Electric current - CORRECT ANSWER✅✅✅flow of charged particles
Ampere - CORRECT ANSWER✅✅✅rate of electrical flow of 1 coulomb of charge per second
C/s
, DC - CORRECT ANSWER✅✅✅Direct current
charges flow in one direction produced by a battery
AC - CORRECT ANSWER✅✅✅alternating current
electrons in the circuit move back and forth
Ohm's Law - CORRECT ANSWER✅✅✅measures electrical resistance, or shows relationship between
voltage, current, and resistance
Current = voltage/resistance
Amperes = volts/ohms
Superconductors - CORRECT ANSWER✅✅✅zero electrical resistance to the flow of charge
Magnetic force - CORRECT ANSWER✅✅✅where a magnet repels or attracts without touching
Magnetic Field (with direction) - CORRECT ANSWER✅✅✅space around a magnet, produced by the
motion of electric charge
from north pole to the south pole
Faraday's Law - CORRECT ANSWER✅✅✅the induced voltage in a coil is proportional to the number
of loops, multiplied by the rate at which the magnetic field changes within those loops
Transformer - CORRECT ANSWER✅✅✅an electromagnetic-induction device consisting of an input
coil of wire and an output coil of wire
Our hypothetical moving positive charges go "downhill" as they move through a wire. Do the moving
charges go faster and faster as they go "downhill"? - CORRECT ANSWER✅✅✅No, resistive forces
quickly match the driving electric force so that the charges move at constant speed
Consider a simple circuit in which there is just one possible path for the hypothetical moving positive
charges. If part of the circuit has a big resistance and part has small resistance, then... - CORRECT
