| Three 5.0 ? resistors are connected in series with a i 3.0 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 three resistors are connected in parallel across the battery equivalent resistance current in each resistor Need Help? Resd 2. 0 is points Sercp1o 18 P 005 MIFB Consider the following figure 7.00 ? 4.00 ? 9.00 ? (a) Find the equivalent resistance between points a and b in the figure. (R-16.0 0) in erence of s4.0 V is applied between points a and b (b) Calculate the current in each resistor if a potential ditf 1 (4.00 ?) “ (7.00 ?) ~ 1 (16.0 n) 1(9.00 n)Explanation / Answer
Problem 1)
When in series,
A) Equivalent resistance Req = 5+5+5 = 15 ohm
B) Current I = 13/15 = 0.867 A. ( Current will be same in series in each resistor)
C) when in parallel,
1/Req = (1/5) + (1/5) + (1/5) =
Req = 1.667 0hm (ans)
------
Net current through circuit
i= V/R= 13/1.67
i= 7.784 A
As all resistance are same so current divide equally,
Current in each resistance given by
i= 7.784/3
= 2.5948 A (ans)
Comment on case any doubt.. good luck
