Answer 3

Current is the flow of charge, and voltage is what makes the charges move

Question 4

What happens in a circuit without voltage?

Answer 4

Without voltage, there cannot be current as there is nothing to cause the charges to move

Question 5

What is the unit and symbol for voltage

Answer 5

The symbol is V and the unit is volts (V)

Question 6

What can the voltage across a cell tell you?

Answer 6

The voltage across tells you about the size of the force on the charges

Question 7

What else does voltage tell you about energy in a circuit

Answer 7

Voltage also tells you how much energy can be transferred across components in the circuit by the charges

Question 8

What is the rating of uk bulbs and what does is signify?

Answer 8
