current

Question 1

the formula for voltage in a parallel circuit?

Answer 1

V=v1=v2

Question 2

the formula for electric current in series circuit?

Answer 2

i=i1=i2

Question 3

the formula for electric current in parallel circuit

Answer 3

i=i1+ i2

Question 4

what is the formula for voltage in a SERIES CIRCUIT?

Answer 4

V= v1 + v2

Question 5

the law of electric charge

Answer 5

like charges repel
opposite charges attract
charged object attract neutral objects

Question 6

static electricity

Answer 6

an electric charge that builds up on surface of the object due to gain or lose electrons( not moving)

Question 7

current electricity

Answer 7

the flow of electric charge (moving)

Question 8

what does a voltmeter measure?

Answer 8

measures the volts across the load

Question 9

a chainsaw transform??

Answer 9

electrical to mechanical

Question 10

what does a blow dryer transform?

Answer 10

heat and mechanical

Question 11

how is lightning form?

Answer 11

1. Negative charges build up on clouds, due to friction

2. negative “jump “ from cloud to Earth when close enough

Question 12

what happens to total electric potential when adding more dry cells if connected in series circuit and parallel circuit

Answer 12

series: each load gets more voltage
parallel: all load will get equal voltage ( the same)

Question 13

What happens as more loads are added to the electric potential for each load in connected in series circuit or parallel

Answer 13

series: each loads gets less voltage
parallel: each loads get the same (full) voltage

Question 14

what happens if more loads are added to the total current if connected in series and parallel

Answer 14

series: it gets slower ( decreases)
parallel: the total current increases
