As we know, if there is a voltage difference =V
Distance =d
Then,Electric field ,E=V/d.
Draw pictures please!! 90. Thunderclouds may develop a voltage difference of about 5 x 10 V....
thunderclouds typically develop voltage differences of about 1 X 10^8V. Given that an electirc field of 3 X 10^6V/m is required to produce an electrcal spark within a volume of air, estimate the length of a thundercloud lightning bolt. ( can you see why, when lightning strikes from a cloud to the ground, the bolt actually has to propagatc as a sequence of steps?)
a) Estimate the voltage of a thundercloud from which lightning strikes theground 200m below. (Assume the ground is at 0v).b) An electric field intensity of 4 x 106 V/m isrequired to get a spark to form in air. If thevoltage applied across a spark plug is 5000V,What will be the spark gap between theelectrodes.(Please give your answer in mm).
PLEASE don't forget to write detail 2 or 3 sentences and pictures explanations. thanks! 5. (30 points) We use rockets to launch sattelites into orbit, and lightening strikes can destroy both. In 1987, exactly this happened with an Atlas/Centaur rocket (it was an unmanned rocket; no one was injured). In this problem, we'll look at how an existing electric field caused an even stronger electric field to develop near the rocket's nose, causing lightening. If you wish to read more...
An electric field of 8.50 times 10^5 V/m is desired between two parallel plates, each with an area of 35.0 cm^2 separated by 3.00 mm of air. What charge must be on each plate? How does the energy stored on a parallel plate capacitor change if: The potential difference applied between the plates is doubled? The charge on each plate is doubled? The separation between the plates is doubled, as the capacitor remains connected to the same battery? The separation...
Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
