Question

differences between series connection and parallel connection

Answer 1

Series circuits are designed so that the current through each component is the same, whereas parallel circuits are designed so that the voltage through each component is the same.

Answer 2

Explanation:

• series connection

1. when three resistors are connected in series we can observe
2. the sum of potential difference of bulb is equal to potential difference we get v=v1+v2+v3
3. the sum of indiviual resistances is equal to their equivalent resistance when resistance is connected in series Req=R1+R2+R3
4. when one resistor in series break down the circuit opens and flow of current cannot take place in circuit

• parallel connection

1. the current flows from battery is equal to sum of indiviual currents drawn by bulbsI=I1+I2+I3
2. the equivalent resistance of the resistors is parallel1/Req=1/R1+1/R2+1/R3
3. in parallel connection there are many paths for the flow of current in the circuit potential difference across each resistor is equal to v
4. the equivalent resistance of a parallel combination i s less than the resistance of each of the resistors
