ann, bees PHYS 102: HW-6 (posted: 03/03/2015, Due: 03/17/2015) cunurt nsider the fol circuit. Each resistance is 100 ohm and the battery is 5v. (a) what is he current through (b) What is the electric potential at point A? Which of the following statements is true about Ohm's law? al It is applicable for resistances and capacitances b) R is applicable only for resistances C It is applicable only for capacitances at is the equation which governs the behavior of capacitances in a circuit? Q CI 4V hat is the relation between magnetic field and magnetic force?Explanation / Answer
The equivalent resistance of this is
[R1 parallel R2] series [R3] series [R4 parallel R5]
= 200 ohms
Thus,
Inet = 5 V / 200 ohms = 0.025 A
which is also the current on R3.
I3 = 0.025 A [ANSWER]
*************************
The R1, R2 combination has 50 ohm resistance. Thus, it takes out
V12 = 50 ohms * 0.025 A = 1.25 V
Thus, at point A, 5 V is diminished by this,
VA = 3.75 V [ANSWER]
