- Show that if two resistors R1and R2are combined and one is much greater than the other (R 1 >>R 2 ): (a) Their series resistance is very nearly equal to the greater resistance R 1. (b) Their parallel resistance is very nearly equal to smaller resistance R2.Why isn’t a short circuit a shock hazard?I don't understand why Rint is in series with Req. I feel like they are in parallel after you've reduced the circuit. Is that because of the junction?
- What are the advantages and disadvantages of placing capacitors in series circuits?A series circuit has 135 watts while a parallel circuit has 15 watts in total. Which circuit has consumed less? Series or Parallel? Explain the reason behind this.What are the disadvantages of using series circuits in domestic wiring?
- An A.C. circuit consists of an alternating voltage source and a resistor only. In this circuit ______. the voltage is in phase with the currentthe voltage leads the current by 90° the voltage lags the current by 180° the voltage lags the current by 90° the voltage leads the current by 180°For a series circuit, what is the terminal voltage of a battery or power supply equal to in terms of the potential differences or voltage drops across circuit components?Why there is a phase shift between the measured voltage VL and current I ?
