How do you convert calories to Joules using a formula? A DC motor consumes 36 MJ of energy when connected to 230 V FOR 2.5 hours. a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor from the mains. c. The current taken by the motor...
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article onhow to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric ...
The current passes through a resistor in a circuit connected across a battery of the potential V is equal to the ratio of the supplied voltage and resistance. As we increase the potential of the battery, the current in the resistor directly increases. Thus, {e...

of ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium then the it's membrane potential is equal to the Nernst ...
Using the Nernst equation, one can calculate the EMF produced under a no-load situation: Where E is the Nerstian EMF generated, R is the Universal Gas Constant = 8.31 J*K-1*mol-1, T is the temperature of the cell in Kelvin, F is the Faraday Constant = 96500 Cmol-1, Z is the ...
Is there a difference in current between two circuits if one circuit has the lightbulbs in series while the other one has them in parallel? You connect a number of identical light bulbs to a battery. What happens to the brightness of each bulb as you add more and more bulbs to the circu...
