Question

why in series combination the current will be the same and voltage be differ but voltage is directly proportional to current so current will also be differ if voltage is differ​

Answer 1

Answer:

Voltage is different but current is same in series combination of Resistances. ... Hence, in the series combination of resistance, the current remains same where as in parallel combination of resistances the current get distributed to each resistance in the parallel.

Answer 2

Ohm's law states that "At constant temperature, current is directly proportional to voltage applied".

The resultant current flowing through a given circuit is deduced and dependent on both the applied voltage and the total resistance.

In above circuit, assuming the applied voltage to be 10V and resistance values as R1=2Ω, R2=2Ω and R3=6Ω.

Then the resultant current flowing through the circuit will be...

I = V/R = (10 V)/(10 Ω) = 1 A

Let us say the applied voltage across the circuit is increased to 20V. (Resistance is constant here)

Now, what happens to the current?

I = V/R = (20 V)/(10 Ω) = 2 A

Hence, current is directly proportional to voltage in a series circuit.
