2.2 Series and parallel circuits

Question 1

2.2.1 Series and parallel circuits

What happens to current, resistance, voltage to components connected in series?

Answer 1

• there is the same current through each component
• the total voltage of the power supply is shared between components
• the total resistance of components is the sum of the resistance of each component

Question 2

2.2.1 Series and parallel circuits

formula for resistance in series circuit

Answer 2

R total = R1+ R2

Question 3

2.2.1 Series and parallel circuits

What happens to current, resistance, voltage in components connected in parallel?

Answer 3

• the total current throughout the whole circuit is the sum of currents through the separate components.
• the voltage accross each component is the same
• the total resistance of the two resistors is less than the resistance of the smallest (individual) resistor.
