In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through the resistor increases. why does this occur? a) as the electrons are sped up, they bunch closer together b) as the electrons have more energy, they vibrate more rapidly c) as the electrons are pushed more by the battery, they move faster through the circuit d) as the distance around the circuit increases, the electrons take longer to travel around

ANSWER:

C) as the electrons are pushed more by the battery, they move faster through the circuit

EXPLANATION:

Electrons move very slowly. When we supply voltage the current through a wire moves which causes each electron to move in the direction of the flow of current, the electrons which were in random motions previously now move in one direction which is the direction of current,the more we supply the current the faster electrons will move in the circuit,which will cause the current to increase with increase in voltage.

C) as the electrons are pushed more by the battery, they move faster through the circuit

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
