What happens to the current in a series circuit?

• The current stays the same

• The current is added

• The current is reduced

• The current is split between the light bulbs

What happens to the current in a parallel circuit?

• The current stays the same

• The current is added

• The current is reduced

• The current is split between the light bulbs

What happens to the voltage in a series circuit?

• The voltage stays the same

• The voltage is added

• The voltage is reduced

• The voltage is split between the light bulbs

What happens to the voltage in a parallel circuit?

• The voltage stays the same

• The voltage is added

• The voltage is reduced

What is resistor?

• Electrical component that is specially made to have a specific resistance

• The measure of the difference in how much energy the electrons receive to move around at different points in a circuit

• The flow of electrical charges

• The movement or presence of electrons

Why voltage is important?

• Because it is the pressure that causes the electrons to move around in a circuit and make the current flow and make appliances work

• To supply energy to be able to make the current flow in electric circuit and make appliances work

• To control the resistance in the circuit

• To reduce the current in the circuit

What is the unit used for voltage?

• Ampere

• Ohm

• Volt

• Meter

Current is measured in....

• Amps 
• Volts
• Ohms
• Coulombs
