- Series combination of resistors
A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel. If the equivalent resistance of this combination is R’, then the ratio R/R’ is -
In series combination which remains constant?
(c) Both current and voltage
(d) Both are variables
Judge the equivalent resistance when the following are connected in parallel − (a) 1 Ω and 106Ω, (b) 1 Ω and 103Ω and 106Ω.
Find the expression for the resistors connected in series and write the two characteristics of it. (Draw figure).
Find the expression for resistors connected in series. Write any two characteristics of a series combination of resistors.
A battery of 9 V is connected in series with resistors of 0.2 Ω, 0.3 Ω, 0.4 Ω, 0.5 Ω and 12 Ω, respectively. How much current would flow through the 12 Ω resistor?
