While designing a circuit that has two resistors connected in series. Given that we have a 20 V battery that will produce a current of 0.2 A their equivalent resistance in series must be 100 Ohm.
Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
For calculating equivalent resistance in series combination.
Re = R1 + R2
For the given problem we have to design and construct a circuit that has two resistors connected in series.
Given that we have a 20 V battery, that will produce a current of 0.2 A
By using Ohm's law.
V=IR
As voltage V is given 20.0 V and current I = 0.2 A
20=0.2R
R=100 Ohm
The equivalent resistance of the circuit should be 100 Ohm
For equivalent resistance in series
Re = R1 +R2
100 =R1 + R2
Thus, the resistor can be in various combinations but the sum of their equivalent value must be 100
For example it can either be 50 Ohm, and 50 ohm or 60 ohm and 40 ohm
