Revive Resistance - Series & Parrallel

In summary, series and parallel circuits have different configurations and affect the overall resistance differently. Series circuits have all components connected in a single pathway while parallel circuits have multiple branches. In series circuits, the total resistance increases with more components, while in parallel circuits, it decreases. The purpose of using these circuits is to control and distribute current more efficiently. In terms of voltage, series circuits divide the voltage among components while parallel circuits provide the full voltage to each component. Adding more components in series increases resistance and decreases current, while in parallel circuits it decreases resistance and increases current.

Perhaps if you showed your working we could help you out.

HINT: You have a system of two simultaneous equations, with two unknowns.
 

What is the difference between series and parallel circuits?

In a series circuit, the components are connected one after the other, creating a single pathway for electricity to flow. In a parallel circuit, the components are connected in multiple branches, providing multiple pathways for electricity to flow.

How do series and parallel circuits affect the overall resistance?

In a series circuit, the total resistance is equal to the sum of the individual resistances. In a parallel circuit, the total resistance decreases as more branches are added, making it easier for electricity to flow.

What is the purpose of using series and parallel circuits?

Series circuits are used to control the amount of current flowing through a circuit, while parallel circuits are used to distribute the current to multiple components. This allows for more efficient and flexible use of electricity.

How does the voltage change in series and parallel circuits?

In a series circuit, the voltage is divided among the components, with each receiving a portion of the total voltage. In a parallel circuit, each component receives the full voltage.

What is the effect of adding more components to a series or parallel circuit?

In a series circuit, adding more components increases the total resistance and decreases the current. In a parallel circuit, adding more components decreases the total resistance and increases the current.
