I have a question for the effect and difference on a DC motor
for the speed( rad/s) in time (sec) if you apply:
1. Nothing (so no charge in the circuit only the mecanic charge
of the generator)
2. A resistant charge (only the resistant is plug in with the
generator)
3. Short circuit (No exterior electric charge but the terminals
are bounds together so an excessive amount of current flow into the
circuit)
4. Capacitive charge (only the capacitor...
1)
What is the difference between the closed center Dc valve and the
open center Dc valve
2) what is the function of the Needle valve with By-pass
check
1. How does the consumer choice work and how does it effect
supply and demand.
2. If the average product price is declining, how does that
impact the production and cost?
3. Does perfect competition work? What is an example where it
does not work?
