Question

Two circuit elements are said to be in series if they share the same voltage. Infinite resistance is equivalent to a voltage source with zero volts. The resistance of a 1.5V battery with a maximum short circuit current of 300m A is 0.45 Ohms. Two circuit elements are in parallel if they share the same current. Voltage is the energy required to move 1 C of charge through an element. In DC analysis, as time approaches infinity, the capacitor behaves as an open circuit. If a capacitor has an impedance of 20 Ohms at 1000 HZ, the impedance is 40 ohms at a frequency of 4000 HZ. If v1(t)=3COS(2t+20) and v2(t) = 2COS(3t+30) are connected in series, the equivalent source in phasor domain is 5e^j50. For the typical receptacle (outlet) in buildings, the average voltage is 170 V. Residential electrical systems are 120/240V single phase; while commercial buildings are 120/240 three phase.

Explanation / Answer

a) In series current remain same ,voltage is different so FALSE
b)False,as infinite resistance equivalent to open circuit and there is alwyas voltage acroos open curcuit when voltage source is connected across it
c)False because R=V/I
   according to this R=5 ohm but given R=0.45 ohm
d)False,in parallel they share same voltage.
e)False that energy is know as work.Voltage is potential difference between two points.
f) True,but this is only for DC circuit
