Current and Voltage in electrical circuits.

Question 1

What unit is used for measuring electric currents?

Answer 1

Amps

Question 2

what flows from positive to negative?

Answer 2

current

Question 3

How much charge flows through a battery delivering a current of 0.5A for 30 seconds?

Answer 3

15C

Question 4

what are currents?

Answer 4

Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.

Question 5

what is voltage?

Answer 5

Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field.

Question 6

what two things ensure that a circuit works?

Answer 6

There must be a complete circuit and there must be no short circuits

Question 7

What are series connections

Answer 7

Components that are connected one after another on the same loop of the circuit are connected in series. The current that flows across each component connected in series is the same.

Question 8

What are parallel connections

Answer 8

Components that are connected on separate loops are connected in parallel. The current is shared between each component connected in parallel.
