1.If I have four resistors in parallel and each of them has a resistance of 40012, if these resistors are hooked to a 9V battery what is current through the battery? (Show all work)

2. If I have four resistors in series each with 40012, that is hooked to a 9V battery what is the current through the battery? (Show all work).

3. How is current distributed in a parallel circuit (you may look it up)?

4. How is current distributed in a series circuit (you may look it up)?

5. Find a practical application for a parallel circuit and a series circuit?

Expert Solution

Answer:
5.Application of Parallel circuits:

  1. Lighting in your house: if any of them is burnt, you still get the others on.
  2. Voltage regulation in a DC rectifying circuit. You add a huge capacitor in parallel with an inverse polarized zenner diode and some other things.

Applicatuon of Series circuits:

  1. Lighting in your house: the light switch is in series with any amount of parallel lamps you want to turn on and off at the same time.
  2. When, within a circuit, you have a power indicator LED, you will put it in series with a resistor to make sure the current through the LED is correct.
