At any one time, the world's total volume of water is in many different forms. It can be liquid, as in oceans, rivers and rain; solid, as in glaciers; or gaseous, as in the invisible water vapor in the air. Water changes states as it is moved around the planet by wind currents....
The unit of resistance is theohm, pronounced om with a long o. The K in the schematics stands for kilohm or thousands of ohms. 10K means the same as 10,000. Meg and sometimes M mean megohm or million ohms. 4.7Meg or 4.7M is the same as 4,700,000. ...
Amperes(ampsfor short) represent the current, or how many electrons are flowing through a circuit. Using the water analogy, this would be the amount of water flowing through the pipe. Ohmsmeasure the amount of resistance in a circuit; the higher the resistance, the more the circuit slows dow...

Question: How many amperes flow through a 60-watt bulb when 120 volts are impressed across it? Power: The total power generated in a complete circuit is equal to the product of voltage and the amount of current flowing in the circuit. Based on Ohm's law, the volt...
Resistor R1 on jack 1 is the 'input resistor.' It sets the amp's input impedance to 1,000,000 ohms (1M) to boost the signal voltage from the guitar. [Bonus info: R1 also functions as the 'grid leak' resistor for Tube V1A's grid. A grid leak drains off unwanted DC voltage to ...
Is a kWh a unit of power or a unit of work? How many amperes flow through a 60 watt bulb when 120 volts are impressed across it? 1. Calculate the current I_1, I_2, and I_3. 2. Calculate the total power dissipated in this circuit. How to convert miles to kilometers with a fo...
Did you know there are many types of resistors? Your electronic schematic tells you that you need a resistor of 100k Ohms. Ok, so you go to an online store to buy one. But there you get all these choices: Thin film, carbon composition, metal film +++. ...
G=11.25×103ohms=8×102siemens Conductance when Current and Voltage Are Known Consider this example: A voltage (V) of 5 volts generates a current (I) of 0.30 amps in a particular length of wire. Ohm's law tells us that resistance (R) can be easily determined. According to the law: ...
I found that the four-dollar DealExtreme module ran nicely, but not excessively, brightly from two AAs through three 91-ohm resistorsin parallel, for an aggregate 30.3 ohms. I couldn't find aroughly-30-ohmresistor for the final assembly, so I used a couple of 16sin series. Small laser ...
