Answer:
What is resistance?
Resistance is defined as a measure of its opposition to the flow of an electric current.
Two types of resistance is observed in an electric circuit:
- Series combination
- Parallel combination
What is series combination?
In series combination, the current flows equally through each of the resistors.
What is parallel combination?
In parallel combination, the current gets divided in each of the resistors.
In case of a combination of 4 resistors:
- For series combination, the net resistance = R+R+R+R = 4R.
- For parallel combination, the net resistance = 1/R+1/R+1/R+1/R = 4/R
Explanation:
Here, R means resistance. It is considered to represent the required formula for calculation.
The net resistance between two points for series combination is obtained as four times the R and for parallel combination it is obtained as 4 divided by R.
