Question

Five 13.0 Ω resistors are connected in series with a 21.0 V battery. Find the following. (a) the equivalent resistance of the circuit?


(b) the current in each resistor?


(c) Repeat for the case in which all five resistors are connected in parallel across the battery. equivalent resistance : current in each resistor :

Explanation / Answer

a) equovalet resitance = 5 x R =5 x 13 = 65 ohm

b) current = V/R = 21/65 = 0.323 A

c) Req = (5/13)^-1 = 2.6 ohm

current in each resistance = = 21/5 x2.6 = 1.615 A
