Current and circuit symbols

Question 1

What is current?

Answer 1

Current is the flow of electric charge

Question 2

When will current flow?

Answer 2

When a circuit is closed (complete) and when there is a potential difference

Question 3

What is current measured in?

Answer 3

Amps (A)

Question 4

What is the current like in a single closed loop?

Answer 4

The current has the same value everywhere in the circuit

Question 5

What is another word for potential difference?

Answer 5

Voltage

Question 6

What is potential difference?

Answer 6

The driving force that pushes the charge around

Question 7

What is the unit for potential difference?

Answer 7

Volts (V)

Question 8

What is resistance?

Answer 8

Resistance is anything in the circuit which slows the flow down

Question 9

What is the unit of resistance?

Answer 9

Ohms (hoarse shoe)

Question 10

The current flow through a component depends on what?

Answer 10

The potential difference across that and the resistance of the component

Question 11

The greater the resistance—

Answer 11

The greater the resistance across the component the smaller the current that flows through it

Question 12

What does total charge through a circuit depend on?

Answer 12

Current and time

Question 13

What is the letter symbol for current?

Answer 13

I

Question 14

What is charge measured in?

Answer 14

Coulombs (C)
