The watts equation for an electrical circuit takes into account the voltage across the circuit V, measured in volts, and the current I, measured in amps, passing through it. In mechanics, the definition of power is the rate of doing work W. It's defined as W...
Substitute the values for the current and resistance for the variables in the equation. Current is measured in amperes, and resistance is measured in ohms. For example, if the the current were 6 amperes and the resistance were 3 ohms, the equation would be: E = (3)(6). Step 3 Solve ...
So, electricity needs a conductor in order to move. There also has to be something to make the electricity flow from one point to another through the conductor. One way to get electricity flowing is to use a generator. Holy Electricity In the late 19th century, electricity truly had a nobl...
According to Ohm’s law, Thus, by using the equation we get a voltage drop across the circuit of 60 volts. Voltage Formula 2 (Power And Current) The power transferred is the product of supply voltage and electric current. Now, put in the above equation we get, (1) Thus, we get vo...
How to convert feet to cm with a formula The angular velocity of a flywheel obeys the equation z ( t ) = A + B t 2 , where t is in seconds and A and B are constants having numerical values A = 2.70 and B = 1.70 . Through what angle does the flywheel turn during the first ...
Ohm's law is represented by the equation I=VR. How would the current change if the amount of resistance decreased and the voltage stayed the same? How much voltage is there in a circuit with a resistance of 12 ohms and a current of 3...
the resistors are said to be in a parallel connection. Because more independent paths for electrons to move through ultimately causes more electrons to flow through the circuit, connecting additional resistors in parallel causes the equivalent resistance of the circuit to decrease. The equation fo...
to calculate the heat dissipated by the cable, we can use theStefan-Boltzmann equation. However, according to the Wikipedia article, this equation describes the power radiated from ablack bodyin terms of its temperature. How can such an equation for the temperature ...
Suppose you want to convert 550 atm into pounds per square inch. Using the conversion formula above, you will get: Value in psi = 550 × 14.695948803581 = 8082.77 pounds per square inchThis converter can help you to get answers to questions like: How many atm are in 550 pounds per square...
2) Choose the right gear: Because the median resistance of the ohmmeter is tens of ohms, and the ohmmeter gauge is used to measure the resistance when the pointer points to the central reading is more accurate, so the selected ratio is one order of magnitude smaller than the estimated value...
