Answer 1

Answer:

Ans 1 If different resistances are joined with each other such that there is only one path for the flow of electric current then the combination of such resistances is called Series Combination.

Ans 2 -Voltage drops add to equal total voltage

All components share the same (equal) current.

Resistances add to equal total resistance.

Ans 3 In series combination of resistors the current is the same in every part of the circuit or the same current through each resistor 

Answer 2

Answer:

1. (i) series combination. When two or more resistors are connected end to end consecutively, they are said to be connected in series combination. The combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances. R=R1+R2+
2. Resistance in series Characteristics
3. In series circuit the current flows in each resistor is same. In series circuit the total resistance is equal to the sum of all circuit resistance. In series circuit when the value of one resistor is increased as a result the total circuit resistance is increases.
4. In series combination of resistors the current is the same in every part of the circuit or the same current through each resistor and in parallel combination the voltage remains constant.
5. The sum of the current through each path is equal to the total current that flows from the source.

We can find total resistance in a parallel circuit with the following formula.

1/Rt = 1/R
