Question

derive the formula for resistance series combination state the characteriest of this combination​

Answer 1

Answer:

In series combination, resister are connected end to end and current has a single path through the circuit but the potential difference varies across each resistor. Thus we can write as, V = V1 + V2 + V3. according to Ohm's law V = IR So, V1 = I R1, V2 = I R2, V3 = I R3.

According to Ohm's law, the voltage drop, V, across a resistor when a current flows through it is calculated by using the equation V=IR, where I is current in amps (A) and R is the resistance in ohms (Ω). This implies that the total resistance in a series is equal to the sum of the individual resistances.

The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3 ...
