In an electrical circuit resistances can be connected in series or parallel or combination of both. Calculate the effective resistance between the terminals P and Q in the above diagram

In an electrical circuit resistances can be connected in series or parallel or combination of both.If R_1 and R_2 are two resistors connected in series what is their effective resistance.

In an electrical circuit resistances can be connected In series or parallel or combination or both:- If R_1 and R_2 are two resistors connected in series whatistheir effective resistance.

Find the effective resistance of the circuit given below:

Resistance are used to reduce the current flow in a circuit. Resistance can be connected in series and parallel to obtain the required value of resistance. Derive an expression for the effective resistance when three resistors are connected in parallel.
